Conventional gutters made of galvanized steel, made by self-taught craftsmen, are becoming less and less common on new houses. The reason is rapid destruction due to corrosion, complexity of installation and lack of precision in the manufacture of parts. Instead of outdated systems, most cottage owners install plastic gutters with their own hands, or order parts with installation made of metal-plastic covered with a polymer film. The service life of the products is from 25 years, and with proper installation, the drain can last up to 50 years.
The plastic from which the parts are made is PVC. The material does not support combustion, is elastic and durable. The products are produced in different shades; you can choose the color so that the gutter installed on the house harmonizes with the color of the facade, or is completely invisible, merging with the color of the decorative cladding under the roof.
Complex drainage design made from factory parts
Advantages of plastic gutters:
- Light weight and easy to install. No special tools are needed to assemble and secure the trays. Lightweight parts are easy to install even alone.
- Durability. Parts made from high-quality polyvinyl chloride do not change color when exposed to ultraviolet radiation and can withstand temperature changes from -40 to +60 degrees.
- Complete system. Manufacturers produce in several standard sizes all the parts needed for assembly: moldings, couplings, bends, funnels and fasteners.
- Availability. The price of plastic roof drainage systems is much lower than similar sets made of metal-plastic, copper or steel.
Color solutions and equipment plastic system
Among the disadvantages of the material is poor resistance to mechanical damage. Therefore, the installation of plastic drainage is carried out only on low buildings: one- and two-story private houses, garages, outbuildings. It is advisable to equip the roof with snow detainers to protect the plastic from impacts when blocks of ice and snow converge.
Plastic drain on a gable roof
Another feature that is taken into account during installation is the large coefficient of expansion of the material when heated. Connections are made with gaps to prevent deformation of parts.

Components of a plastic drainage system
Before purchasing plastic parts for a drainage system, it is necessary to design the structure:
- Calculate the length and determine the number of horizontal lines under the roof for installing trays.
- Plan installation points for connecting horizontal lines with vertical pipes
- Determine the size of the products: tray cross-section and pipe diameter.
Rules for constructing a drain
Before calculating the number of elements of a plastic drainage system, a diagram is drawn up: marking the installation lines of horizontal trays and vertical drainage outlets. The complexity of the design depends on the geometry of the roof and the number of slopes.
Simple circuits placement and direction of water drainage lines from roofs
The most economical scheme - for simple gable roof. Measure the length of the overhang - if the footage of one slope does not exceed 10 m, then to arrange the drainage of water from the roof it is enough:
- Two horizontal branches.
- Two funnels connected to a pipe.
An example of gutter planning for a roof with a protruding overhang
For roofs with complex design plan horizontal sections for each slope, as well as for protruding cornices and balconies. Installation is complicated by the need to calculate the number of connectors for areas with non-standard geometry: semicircular protrusions, corners (internal and external).
After drawing up the layout of the lines, they begin to select the standard size of the parts. To determine the optimal cross-section of the tray and the diameter of the pipes, it is necessary to calculate the area of the roof slope. There is no need to calculate the area of the entire roof surface with an accuracy of square centimeters: it is enough to find out the footage of the largest slope.
Compliance with the standard size of parts of the roof area
For most private houses, the optimal size is: 100 - 120 mm gutter cross-section and 75 - 100 mm pipe diameter. There is no point in saving on purchasing parts with a minimum diameter: during heavy rainfalls, the system may not be able to cope with a large volume of water.
Calculation of the number of main parts: pipes and trays
Calculation of molded parts is the determination of the number of finished gutters and drainage pipes for arranging the system. Standard length for all finished products is 300 cm.
Details of horizontal lines and downpipes
The footage of the gutters is equal to the total length of the roof slopes where installation is planned, with the addition of up to 10% of the margin. A minimum margin is necessary to avoid joining several short sections in a row. The fewer connections, the more reliable design.
Calculation of the number and length of short segments
The pipe footage is determined as follows: the height of the house from the edge of the roof to the installation point of the outlet or connection to the storm water inlet is multiplied by the number of installation points for vertical gutters.
In addition to the main moldings, it is worth determining in advance whether it is necessary to install protective grilles. When installing the system on low roof, especially if there are trees nearby, it is better to close the gutters.
To protect plastic drainage trays from damage by ice and snow, install a heating electric cable. Thermal cable is sold separately.
Connections and fasteners: calculating the quantity and choosing the type of parts
Installation of plastic roof gutters can be done in 2 ways:
- When installed on a roof without roofing, attach the trays to the rafter sheathing - under upper layer coverings. In this case, long adjustable brackets are used.
Types of fasteners for gutters and pipes
- The weight of the plastic trays allows the system elements to be attached directly to the windshield (frontal) board if installation is carried out on a covered roof. Short non-adjustable hooks are used for fastening.
Tray holders are installed every 50 - 60 cm. Increasing the distance between the brackets in order to save money is not practical. At heavy loads When the snow melts, a long, loose section may not be able to support the weight of the water.
Number of hooks for attaching the gutter
In addition to the brackets, the required number of parts is calculated:
- Funnels: according to the number of planned drain points into the pipe on the diagram. Each funnel needs a protective mesh funnel if the trays are not planned to be covered with grates.
- Connectors: every 3 m when installing solid parts, with the addition of 2 pieces for each short section.
- Corner parts: according to the number of external and internal corners.
Important! Pay attention to the way the corner is connected to the tray. If the corner piece is attached directly to the edge of the tray, no additional connectors are needed. If the corner is not equipped with factory fasteners, you will have to purchase 2 couplings for each part.
When choosing components, try to choose a system with adhesive-free connectors: such products make it possible to compensate for linear thermal expansion.
Ready-made formulas for calculating the number of parts and pipe footage
When calculating the number of pipes for vertical installation, the factory footage is taken into account: some manufacturers offer moldings 3 and 4 m long. Special clamps and screws are purchased for fastening to the wall. At the junction with the funnel, rotary products are installed - 2 elbows each.
Underground outlet: parts for assembly
2 ways to drain water from the roof away from the foundation:
- Place the outlet into an open concrete storm drain channel.
- Install a rainwater inlet connected to the storm drain under each drain.
The second method is more reliable. Water flowing down the pipe will not fall on the blind area and soil. To connect the rainwater inlet to the pipe, use an open and closed method.
Stormwater inlet under the drainpipe
With the open method, the exit is organized using an elbow installed in the center of the receiver at a height of up to 30 cm above the ground. When closed, the pipe is fixed directly at the top of the receiver.
The number of storm water inlets is equal to the number of vertical outlets. Receivers are made of plastic, equipped with blind covers with holes for a standard size pipe, or the open top is covered with a grill.
Do-it-yourself assembly and installation of a PVC drainage system
Before the beginning self-assembly plastic drainage, be sure to check the presence and condition of all parts. Special attention It is worth paying attention to the quality of seals and connecting elements. The rubber should be dense, elastic, and fit firmly to the body. An uneven color with whitish spots indicates that the product was produced a long time ago. It is better not to use such a gasket: the connection will begin to leak.
Preparation: what tools you will need
The tools that are necessary to install a plastic drain with your own hands can be found in every home:
Installation Tools
- Hacksaw for cutting parts and sandpaper to finish the edges. A jigsaw will work instead of a hacksaw. It is better not to use a jigsaw or grinder: the temperature may cause the plastic to become deformed.
- Screwdriver and screws for fastening parts.
- Chalk, ordinary linen thin cord or thread, tape measure, level, pencil or marker for marking.
Marking installation lines for trays and fastening holders
Installation of horizontal sections of plastic drainage begins with marking lines for fasteners. When installing short hooks on the wind board, it is necessary to draw a line along which the brackets will be secured.
To correctly mark the starting point of the line, you need to step back 15 cm from the edge of the front board. The minimum distance between the edge and the center of the first bracket is 5 cm. Be sure to calculate the distance from the edge of the overhang to the center of the hook.
If we draw a conventional segment as a continuation of the roof slope, then the distance between the outer edge of the tray and conditional line should be up to 3 cm. The edge of the roof should hang over the center of the tray.
Position of the tray in relation to the edge of the roof
After determining the installation point of the first fastening, mark the installation point of the last hook on the opposite edge. Between the two extreme points it is necessary to make a height difference so that the gutter is installed at an angle towards the funnel.
The slope is 2 - 4 mm per meter. If the distance between the extreme points is 10 m, then the height difference should be 20 mm. The installation line is marked using a coated cord or thread stretched between the extreme points.
Distance from connector to fastener
Attach hooks every 50 - 60 cm. Make sure that there is at least 2 cm between the bracket and the edge of the planned connectors and funnels.
How to make the correct slope when installing long brackets on the deck
If a fastener with an extension is installed, the slope is formed by bending the required length of metal extensions. Numbered extension cords are laid out in a row, close to each other. From a straight line drawn through the mounting point of the first extension, mark the required height difference on the last bracket.
The brackets are attached to the outer board of the rafter sheathing or directly to the rafters if the distance between them does not exceed 80 cm. When installing, bend the hook for the tray down according to the markings.
Assembling the structure: connecting gutters and installing connectors
Installation of plastic drainage trays is allowed:
- With assembly and simultaneous installation on brackets.
- With pre-assembly and installation of the finished line into holders.
The edges of the gutter are muffled. To do this, install a plug with a seal in the grooves on the edge of the tray. To strengthen the connection, use plastic sealant (for external use) along the entire length of the gasket of the part. Press the plug.
The trays are connected to each other with special connecting parts. The couplings are installed under the edges of the trays so that there is a gap in the center. Most long connectors have stops on the inside that prevent the edge of the tray from being installed incorrectly.
Short connectors require the use of sealant. 3 lines are applied to the rubber gasket: in the center and along the edges. Pressed against the trays. Remaining glue must be removed.
Corner connector with gasket and joint markings
Some manufacturers mark the joint lines inside the connecting parts indicating the air temperature at which installation is carried out. This solution allows you to accurately maintain the distance between adjacent trays to dampen thermal deformations.
The trays are inserted into the groove connectors of the brackets at an angle, and the chute is turned until it clicks.
Funnels: how to attach them to trays correctly
At points where the installation of vertical plastic drains is provided, funnels are attached to the gutters. It is easier to install funnels with connecting horizontal sections with your own hands. The design does not require cutting the gutter, and the connection is made in the same way as joining horizontal sections: using seals and locks.
The hanging funnel is installed after preparation. A hole in the form of a cone or oval is cut out at the bottom of the gutter. The edges must be cleaned until smooth. If nicks or sharp protrusions remain, the edge may damage the rubber of the gasket.
Installing a hanging funnel with locks
Put on the funnel and secure it with locks. Use sealant. A strip of glue is applied around the entire diameter of the hole and the funnel is pressed against the gutter.
Branch from the funnel to the drainpipe
To install the transition from a funnel to a plastic drainpipe located near the wall with your own hands, you will need 3 parts:
- 2 bends – plastic elbows.
- 1 straight segment connecting the rotating parts.
Organization of the transition from funnel to pipe
A connection is attached to the funnel. Be sure to seal the straight section along the outer diameter with sealant. Press the knee tightly. The second outlet is installed in the direction from the pipe to the funnel. Measure the distance between the connectors. Cut a piece of pipe and connect the bends.
Tee for connecting two gutters with one outlet
If two horizontal lines are connected to one pipe, then a tee with a branch for the second branch is installed at the connection site.
Assembly and fastening of vertical pipes
The distance between the clamps holding the pipe should not exceed 2 m. The rings are attached to the wall in 2 ways. If the wall surface is plastered, use screws 10 cm long. When installing on insulation, screws 16 cm long are used.
The pipes are connected on a horizontal surface. Use connectors that are installed with the wide part facing up. The upper section is inserted into the socket until it stops or until it clicks. The lower part of the connector is inserted into the next section of pipe, leaving up to 10 - 20 mm of power reserve.
The pipe is clamped with a clamp. An outlet is connected to the lower part to drain water into the rainwater inlet.
Installation of storm water inlets
Storm water inlets are installed in the ground so that the middle of the drain is in the center or at a distance of 1/3 from the edge of the container. If you use plastic receivers with a pipe connector, install them strictly under the drain. The top of the container should be flush with the surface of the blind area.
Dig and fill the hole with solution. Installation on a sandy base or crushed stone backfill is also allowed.

All stages of self-installation of a plastic drain: from attaching brackets to fixing the drainpipe.
It is not difficult to assemble a PVC drain yourself if the roof structure is a simple gable roof and the building height is 1 floor. When installing on complex roofs, mansard roofs, problems often arise with joining parts on uneven, protruding areas. Therefore, it is better not to skimp on professional assembly.
For arrangement drainage systems have been in use for a long time plastic elements. Contrary to popular belief about their unreliability, plastic gutters are much superior to traditional ones in terms of their characteristics. metal parts. Besides the good ones technical parameters, plastic components for drainage systems are also quite affordable, which makes them an extremely profitable purchase. This article will discuss plastic roof gutters and their features.
Device and equipment
For the production of plastic gutters, polyvinyl chloride is used - a polymer material obtained by thermoplastic processing. All components of drainage systems are made from this material.
Installation of plastic gutters is carried out using the following elements:
- Gutters. These elements are necessary to receive and transmit water flowing from the roof slopes to the water intake funnel. Plastic gutters differ from metal products in a wide variety of sizes, which allows you to choose the best option for a particular situation.
- Gutter coupling. The coupling allows you to connect individual parts of the gutter. This element is small in size, and its installation requires silicone sealant or a rubber gasket.
- Corner. The angles allow you to direct the plastic gutter in the desired direction. In construction, parts with a right bend angle are most often used, but if it is necessary to create a different angle, a non-standard option can be found on the market.
- Brackets. These elements are fasteners that support the gutter. The holders themselves are attached to the sheathing boards.
- Stubs. These parts of the drainage system allow you to block water from accessing the drain through the edge of the gutter, located on the other side of the funnel.
- Water intake funnel. This is an essential element of any drainage system, which collects water from the gutter and transfers it to the drain pipe. Visually, this part is a small trench that turns into a funnel.
- A drain pipe. This pipe is installed vertically and ensures that the liquid collected by the funnel is transferred to storm drainage.
- Drain pipe end. This element of the drainage system is necessary so that the flowing water slows down as it drains. The tip has a curved shape, due to which the speed of liquid movement is dampened.
- Brackets for drain pipe. The brackets are attached to the wall of the building at a certain pitch, after which a pipe is inserted into their outer rings.
When choosing plastic drainage elements, you need to remember that there are no strict standards regarding the size of parts. To ensure that plastic drainage pipes are compatible, it is worth purchasing full set from one manufacturer.
Advantages of plastic drainage
Plastic drainpipes have the following positive qualities:
- Completely resistant to corrosion. Like all polymers, polyvinyl chloride is completely resistant to oxidation, so it can be successfully used for collecting and transporting liquids.
- Light weight. Light weight is another quality common to all polymer products. Thanks to this quality, installation of plastic drainage can be carried out without additional reinforcement of the roof truss system.
- Low noise level. Of course, there will still be noise from falling and flowing water, but if we compare the acoustic properties of metal and plastic products, the latter will come out ahead by a significant margin.
- Easy to install. Plastic elements of drainage systems are very easy to work with, so you can easily install them yourself. In addition, the installation of plastic drainage is greatly simplified due to the low weight of polymer products.
- Low cost. Plastic drainage systems are much cheaper than metal ones, and there are much fewer problems with them.
- Long service life. Components made of polyvinyl chloride under normal operating conditions can easily last about 50 years without any complaints.
- Variety of colors. If necessary, you can easily select plastic parts, matching the color to the existing exterior of the building.
- Possibility of self-adjustment. Even when installing a drain with a complex configuration, problems will not arise - if necessary, plastic parts can be easily cut with a hacksaw without losing their characteristics.
Disadvantages of plastic drains
Plastic has its negative qualities, which you need to know about before installing a plastic drain:
- Low mechanical strength . This is one of the most serious disadvantages of plastic products. A huge number of plastic drainage systems simply broke down as a result of heavy snowfall. If the region in which construction is taking place has a significant level of precipitation, then it would be better to choose a more durable materials for arranging a drainage system.
- Necessity preliminary calculations drain. In order for the drainage system to operate normally, it must be designed and calculated before installation. Otherwise, the throughput of the structural elements may simply not be enough, and the entire system will have to be reinstalled using larger parts.
- High degree of thermal expansion. When exposed to high or low temperatures, the plastic changes in volume, which, if the elements are rigidly fastened, may well lead to their deformation. To avoid this phenomenon, plastic parts must be secured using the floating method or using rubber gaskets.
Installation of gutters and PVC pipes
In order for the drainage system to perform its functions efficiently, it must be properly installed. Naturally, before this, the building must have a rafter frame and sheathing protected by waterproofing material.
Installation of a plastic drainage system is as follows:
- First, you need to mark the gutter attachment points on the front board so that the slope is from 3 to 5 degrees per meter of drainage (to maintain the slope, you should use a cord);
- Next, the brackets are attached, and they need to be installed so that the overhang of the slope is exactly in the middle of the gutter - this placement will protect the drainage system from snow;
- The installation process must be started from the point where the funnel will be located, measuring 15 cm in each direction and installing brackets at the resulting points;
- All brackets, except the first ones, are installed in increments of about 50 cm, and installation is carried out towards the funnel;
- A funnel is installed on the brackets, after which you can begin installing the gutter, having previously adjusted it to required dimensions;
- When installing the gutter, it is necessary to use sealant or rubber connecting elements;
- The brackets necessary for fixing the drain pipe are attached to the wall vertically in increments of one meter;
- Next, a drain pipe is mounted, which must first be attached to the funnel, adding the necessary part with separate parts of pipes fastened with couplings;
- Bottom part the drain is equipped with a curved tip, the edge of which should be located at a distance of no more than 30 cm from the ground.
It is advisable to install PVC gutters at temperatures above +5 degrees. The fact is that at average temperatures the plastic will take its normal shape. It is also worth remembering about changes in the size of polymer parts as a result of temperature changes - this moment must be compensated by leaving small gaps when tightening screws or using special elements, providing such a gap. Some craftsmen even make drainage from plastic bottles, which is free.
Conclusion
Plastic drainage is a reliable and convenient system, which, with a high-quality selection of components, proper installation and normal operating conditions, can last for several decades.
Installation of plastic gutters is perfect option for those who want to independently protect the roof of their house from excess moisture. The function of the drainage system is to quickly remove precipitation from the roof of the building. How it is installed (correctly or incorrectly) will determine how long and how efficiently the system will function. In fact, installing a drainage system with your own hands is not difficult. The main thing is to follow the instructions for assembling and installing system elements. The installation of plastic gutters can be structured into several stages.
Installation of roof gutters: preparatory stage
The advantages of plastic gutters are as follows:
- great popularity and competitiveness;
However, plastic gutters also have disadvantages. Firstly, this is the fragility of the structure. Secondly, if the system elements are installed incorrectly, the plastic may change color or shape.
First you need to do all the calculations. To calculate the diameter and length of the system, you need to take into account the height of the building and the area of its roof.
Calculation template: building height=4.5m, roof area=9m. With these initial data, the installation of plastic gutters will require the following:
Three-meter gutters (3 pieces),
— gutter plugs (right and left),
- funnels (2 pieces),
- brackets - necessary for attaching the gutter (16 pieces),
- plastic pipe 3 m long (4 pieces),
- fastening the pipe to the wall (10 pieces),
— 45-degree pipe turns (6 pieces).
1) Construction knife
Installation of roof gutters: installation stage
It is not difficult to install a drainage system with your own hands. First you need to decide on the location of the drainage system. In places where it is planned to install drain pipes, funnels should be installed.
The fastenings – brackets – should be evenly distributed over the entire surface of the wall. Between them you need to maintain a distance of 500-600 mm.
The DIY drainage system continues with the installation of gutters.
Many people prefer to assemble gutters with plugs and funnels directly on the ground. After which the entire structure is lifted up and attached to the brackets. It is difficult to do this on your own, alone. Therefore, it is best to assemble the drainage system at the top in stages.
The gutters are mounted from the funnel, and they are joined using connectors. The edges of these elements are entered up to a special mark.
If you need to cut the gutter to a given size, then in this case you can use a hacksaw. The burrs are removed with a file.
Plugs are installed on the end side of the gutters. The distance from the gable board to the cap must be at least 30 mm.
They begin to install the drainage system with their own hands from the funnel. If the roof extension is small, it is recommended to use a coupling.
In order to connect the pipes, couplings should be used, as mentioned earlier. It is necessary to leave a gap in the coupling when entering the down pipe. A bracket (with a clamp) is installed under this element.
Tees are mounted similarly to couplings, as shown in the photo below.
Then the elbow is glued to the lower pipe.
Next you need to install a storm drain. It is installed in the place where water will come out of the drainpipe. To do this, you will need polymer pipes that are discharged into the well. You need to dig a trench from the house and install a filter well. Pipes are laid in the trench. One end of the pipe will be installed in the filter receiver, and the other in the pit. The pit can be purchased at a specialized store. After the pipe is laid in the trench, the storm drain is concreted.
This completes the installation of plastic gutters.
Do-it-yourself plastic roof gutters: 5 steps to a quality drainage system
The most serious competition to metal or galvanized gutters today comes from modern plastic ones. They performed remarkably well in difficult situations. climatic conditions: They are not afraid of Russian frosts, equator heat, or impressive snowfalls. And even the most demanding buyer will like their shapes, colors and designs! It’s easy to emphasize with such additional elements style decision any home, if you only understand the technology of their installation.
Therefore, we offer you the latest information on how to install plastic roof gutters with your own hands - from choosing hooks to constructing a system of unusual design. And in just 5 steps!
Here's a good overview of modern plastic gutters:
Step 1. Choosing a high-quality drainage system
Modern drainage systems must meet a number of requirements, including not only mechanical strength, but also corrosion resistance and maximum tightness. That is why today plastic gutters are considered the most practical.
Their main advantage is that they are easy to match not only to the roof covering, but also to the facade, and the color range is the richest among other materials. And not only! But it is also important to know about certain disadvantages that can nullify all your work.
Advantages and competitive properties
Modern plastic drainage systems include horizontal gutters, vertical pipes, elbows, pipe couplings, external and internal corners, funnels, connecting elements, brackets, clamps and plugs for gutters. Also different manufacturers plastic gutters are supplemented with their own details, such as a garbage catcher.
The plastic drainage system is also good because it can be purchased with rubber seals. And this makes it easy to correct any installation errors, especially if you are taking on the drain for the first time - unlike the adhesive system:
In addition, the plastic drainage system does not corrode or scratch. And, if the drain is still torn off, then the deformed plastic gutter or pipe can simply be put back in place, when the metal one will have to be completely replaced.
And finally, another valuable advantage is the light weight of such gutters. Most often, industrial gutters are 50 or 100 centimeters long. In drainage systems, gutters are used with a height of 7.5 to 15 cm and a width of 10 cm.
Annoying shortcomings and quality issues
Of the minuses, we note that plastic, due to the peculiarities of its structure, can easily bend and deform during periods of temperature fluctuations. And especially hot weather The plastic gutters even sag a little between the hooks if the fasteners were placed incorrectly and too far apart.
Although, according to modern manufacturers, these disadvantages are insignificant compared to the advantages of plastic gutters. But when the time comes to purchase such additional elements, you will encounter the following issues on the market: poor plastic that easily bursts in the cold or blooms, poor-quality connections between pipes and gutters, and poorly thought-out details. And there may be a misconception that plastic gutters were still of poor quality, and there is nothing better than original galvanization.
In fact, it is precisely because of these features that special materials are added to the composition of plastic for the production of such products today. chemical elements, which allow the drain to acquire immunity to ultraviolet radiation. For example, among the modern products on the Russian market, the Ruflex drainage system from Denmark has appeared, which was developed specifically for the climate of our country, similar PVC drains from the Polish company Gamrat, the English Hunter, the Dutch Galeco, the Russian Ruplast and the Danish Aso Plastmo. And Ruflex gutters are considered especially durable and resistant to ultraviolet rays, the plastic formulation of which includes specially developed additives.
And modern PVC gutters are coated with a layer of acrylic or titanium dioxide during the production process. This is called the co-extrusion method, and this approach maximizes the resistance of normally brittle PVC to chemical rain, ultraviolet radiation and frost. Moreover, the plastic of the gutters is painted over during the manufacturing process, in its entirety, and therefore the scratches on it are not only not noticeable, but also harmless.
In a word, a modern plastic drainage system is not made from unreliable and flexible plastic, as many still think, but from special non-plasticized and impact-resistant PVC new technology. These are the most modern gutters that last 50 years! That is why it is so important to purchase gutters from well-known companies that value their reputation, and not skimp on quality.
Standard configuration
In addition to the main gutters and pipes in modern system plastic drainage system includes funnels, brackets, bends, plugs and even nets for retaining debris:
Modern PVC gutters are assembled using rubber seals or glue. The difference between these methods is huge: the adhesive connection is bad because it is quite difficult to correct if you make mistakes, and it does not compensate for thermal expansion at all, but rubber copes with this 100%.
Therefore, the drains, which are connected by seals, easily move during thermal expansion and allow you to replace at least all the parts at any moment:
Step 2. Select the desired mount
Each bracket is selected to the cross-section of the plastic pipe and according to certain parameters, such as installation method, planned load and aesthetic considerations. Therefore, there are brackets for gutters with square, trapezoidal, round cross-sections and holders for pipes with unusual shapes.
For example, a standard fastening for plastic gutters looks like this:
Most often, plastic hooks are used for plastic drainage systems. The entire structure of the bracket is reinforced by vertical ribs, and they are able to withstand quite heavy loads.
But hooks for a plastic drain do not have to be made of the same material; metal is also great:
But most often, plastic gutters are made in the form of a cylinder, rectangular box or triangular prism:
You have several options for attaching a plastic drain:
So, the fastening is in place, we move on to installing gutters and vertical elements.
Step 3. Install hooks and gutters
You can install plastic gutters on the roof only when the temperature outside is more than 5 degrees Celsius. And the technology itself is quite simple:
- On the last board of the eaves overhang, which completes the sheathing, mark the position of future drainpipes.
- Then the outer brackets are attached so that the gutters then have a slope of 2 to 5 mm per linear meter towards the receiving funnel.
- After this, pull the twine (or strong thread) onto the installed holders and make markings.
- Using a plumb line, we check the verticality of the bent backs of the holders.
- We finally secure the fasteners using galvanized self-tapping screws.
- At the end of the work, the gutters must be closed with plugs and sealed with silicone sealants.
Look how simple it really is:
There is only one rule: fasteners should not interfere with the free movement of the gutter due to temperature expansions.
Step 4. We cut in the funnels and attach the elbows
Now let's figure out how to competently proceed to installing funnels and vertical drainpipes:
You need to connect plastic gutters together like this:
- Insert the rubber seal with the ribbed part facing up. It should not reach just a centimeter from the edge of the connector.
- After this, align the connector symmetrically in the center of the gutters so that there are 3-4 millimeters between the gutters.
- Pull the front part towards the connecting channel until the lock snaps into place. The gutters must be inserted into the curl of the corner 30 cm deep.
- After this, the lock must be locked and the latch must be returned to its original position.
- And finally, be sure to install additional hooks at a distance of 10-15 centimeters from such connections.
- Attach the plug to the end of the gutter and, using pressure, push it inward so that the rubber seal is between the chamfer and the gutter.
- Next, the plug can be pressed on with a mallet so that its rear “ear” closes inside. Now turn the funnel towards the gutter and bend the clamp plates. Insert special “spiders” into the funnel to help prevent debris from clogging the drainage system.
- Now secure the joints with two 4 by 6 mm rivets.
- To seal such a connection, purchase special glue. The back side of the plug will be fixed with a blind rivet.
Now check the strength of the finished ones horizontal elements. Pay attention to the fact that if you hear creaking from already installed gutters, it means there is a problem. This material itself does not creak, it’s not wood. This is a sign that the pipe is changing under the influence of temperature, and something is touching some kind of obstacle.
For example, in some place the holders are poorly secured or they are in too tight contact with it. In this case, simply lubricate all fasteners, in 80% of cases this is enough. If you are dealing with plastic accessories, then just check all connections for quality of installation.
Step 5. Connecting the vertical elements
At this stage, we move from the funnel to the drainpipe - using two universal bends. If your eaves overhang is more than 25 centimeters wide, then install a drainpipe between the knees. If less, then don't worry.
We attach the pipes to the wall. To do this, drill a hole in it for the dowel and install it. Turn the hardware through a special decorative trim, which should be turned in reverse direction and press against the wall. Screw the nut onto the hardware so that you can see 5 millimeters of its thread. Also screw in the back of the pipe and secure the elbow.
At the bottom of the riser, organize a pipe outlet using special adapters and pipe connectors. To do this, you will need two cuttings of pipes that will not have a connecting raster.
To make it easier for you to understand the process, we have prepared detailed step-by-step master classes for you:
To form a more complex configuration, you will need to connect a pair of shapes in an L shape or at an angle of 90 degrees. Please note that in connecting couplings for plastic drainage systems, manufacturers provide installation space. It allows you to compensate for changes in the linear dimensions of the drain.
And finally, it is plastic gutters that are most often connected to the rainwater collection system that is used for greenhouses:
Roof drainage systems
To prevent water from the roof from washing away the foundation, a drainage system is installed. They are made from different materials, more or less expensive, but in general, the costs are substantial. You can save a little money by assembling the drain yourself. The features and installation procedure will be discussed further.
Types of drainage systems
The most famous and common roof drains are made of galvanized metal. They may not be as attractive as more modern options, but they are reliable and inexpensive. And this is important. What’s also good is that if you have the skill of a tinsmith or just have “straight” hands, you can make a drain out of galvanized steel with your own hands.
General view of the drain (storm drain, roof drainage system)
If we talk about other metal systems, then two of them belong to the elite category - copper and an alloy of zinc and titanium. They are certainly durable, but the price is very high. There is a more democratic option - metal drainage systems with polymer coating. They are quite affordable in price, you can’t fault them in appearance, and in durability - it depends on the manufacturer. If the technology is followed, they will happen for many years.
There is another type of roof drainage - made from polymers. They can withstand ultraviolet radiation, frost and heat, are highly durable, and look good. The disadvantage can be considered quite high price, especially European manufacturers. However, there are good options in the low-cost systems category.
Composition of drainage systems
Gutters are located under the roof overhang. They are mounted on special brackets that hold the system. Since the storm drain is located along the entire perimeter of the roof, there are corners - internal and external. All these elements must be connected tightly; for this there are gutter connectors with rubber seals. These elements are often considered unnecessary. Then the gutters are laid overlapping with an overlap of at least 30 cm and connected with self-tapping screws.
What elements does the drainage consist of?
To drain water, holes are made in the gutter into which funnels are inserted. Attached to funnels drainpipes. If the roof overhang is large, the pipe must be made curved. For this, there are maple or universal rings (from some manufacturers). The drainpipe is attached to the wall of the house using special clamps, which have the same color as the entire system.
A system of the required configuration is assembled from all these elements. If you decide to buy ready-made elements and then assemble the gutter yourself, the best solution is to have a house plan with dimensions on hand. Using it, you can quickly determine the composition of the system and calculate the required number of elements.
Installation features
Most of the questions arise about attaching brackets for the drain. It must be said right away that they are installed taking into account the fact that the gutters should have a slight slope towards the funnels. The minimum recommended slope is 3 mm. If you want the water to drain faster, you can make it larger - up to 10 mm.
If the length of the roof gable is less than 10 meters, the slope is made in one direction. If it is more, either they put an additional funnel (and a drainpipe) in the middle and form a drain to it, or the gutter in the middle of the pediment has the highest point and the slope goes from the middle in both directions.
Organization of drainage slope
When installing a drain with your own hands, you usually do this: nail the bracket in the very high point. Then the lowest one is nailed, taking into account the planned slope. A twine is stretched between them, along which all the others are attached. One recommendation - before forming a slope, check the horizontality of the line you are focusing on. Usually this is either a front (wind) board. Unfortunately, it is not always perfectly level. So check the verticality, and preferably with a hydraulic level or a level; in extreme cases, a bubble one will do, but it is long - at least a meter. You won’t be able to find your bearings with shorter ones at longer lengths.
Number of brackets and methods of attaching them
The number of brackets for installing a drain is calculated simply: the distance between two adjacent ones should be 50-60 cm. Divide the total length of the wall by this distance. To the resulting figure we add one (extreme bracket) and get the required quantity for one wall. All others are calculated similarly. If the building has a non-linear shape, you will have to count one by one - the corner elements must be supported on both sides.
Methods for attaching brackets for roof drainage
Now directly about the methods of attaching the brackets. There are three possibilities:
- Nail to the roof rafters. This option is good if the roofing material has not yet been laid - there are no problems with fasteners.
- Install on wind board. If plastic moldings are chosen, this is the only option. In other systems - one of the possible ones.
- To the outer board of the sheathing or flooring under the roofing material (if it is solid). This method is also used before the roofing material begins to be laid.
Roofing material should not protrude more than half of the gutter
Once again, please note that the brackets are nailed taking into account the created slope. If they are made of metal, they are bent using improvised means or a special tool - a hook bender (sold in the same place where gutters are made). In this case, the gutter must be positioned so that the roofing material ends before reaching half of the gutter, and it is better that it is in the range of 1/2 - 1/3. This way, most of the gutter “catches” water, which is important during heavy rainfalls.
At what level should I mount it?
Now about how high to raise the gutter to roofing material. If there is not much snow in your region, or the roof has a large angle of inclination, so that snow does not accumulate on it, you don’t have to worry too much and attach it wherever you like. Otherwise, the gutter must be lowered so that when the snow melts, the drain does not “go away.”
In the figure, the approximate trajectory of the melting snow is indicated by a dotted line. The far edge of the gutter should not intersect with it. By the way, it should be a couple of centimeters lower than the one located closer to the house.
If you cannot lower the gutter lower, you will need to install snow guards on the roof. They prevent massive snowfall. The snow gradually melts and comes off in small fragments, without harming the storm drain.
This is what a massive snow melt looks like. As you can see, the storm drain bracket does not interfere (this is a fitting)
Gutter installation
Gutters are placed in fixed brackets. There are two systems with different sequences of actions. The first has a specially formed groove at the edge of the gutter. The ends of the brackets are threaded into this groove, then the gutter is turned into place, secured with special tongues on the brackets. If you look at the photo, it will become clearer.
Installation of a gutter from the outer edge
In the second system, installation begins from the side of the gable board. The far edge of the gutter is inserted into the locks located there, then pressed alternately into the locks on the front of the brackets.
Installation of gutters using the second system
Two fragments of the gutter must be connected using a special connecting element with rubber seals. But their cost is quite high, so two gutters are simply laid overlapping with an overlap of 30 cm (make sure that the joint is located along the water flow). For greater tightness, you can lay a strip of rubber between the two gutters and connect them with ordinary self-tapping screws (or with washers and rubber gaskets). After installing the gutter, its edges are closed with plugs.
Plugs are installed on the edges of the gutter
Funnel fastening
Having assembled and installed the gutter on the brackets, the installation of the drain continues by installing funnels. They are placed in the lowest areas. If the funnels are located close to the corners, at a distance of about 20 cm from the edge of the gutter, a hole is cut out with a hand hacksaw. It is better not to use a jigsaw or grinder - there is a high probability that the cutout will be too large.
Installing a drain funnel
A funnel is attached to this cutout, clinging to the outer edge of the gutter. Then it is wound up to the second edge and fixed there with special clamps.
Installation of drainpipes
Drainpipes are attached to the funnels. If the roof overhang is large, a rotating element is attached directly to the funnel, which allows the pipes to be brought closer to the wall and secured there. For fastening there are special clamps painted in the same color as the entire system. They are there different designs, but mostly they have a latch so that they can be dismantled without removing the screws that secure the pipe to the wall.
Two ways to assemble drainpipes
The clamps are installed at a distance of at least 1.8-2 m from each other. At the bottom, the drain can be led directly into drainage system(if it is located nearby). If there is simply a blind area around the foundation, the drainage pipe ends with a rotating element that diverts water from the foundation to a distance of at least 20 cm.
Rules for fastening drainpipes
In principle, you installed the drain yourself, but there is one more detail that will make operation much easier. A metal (preferably stainless) mesh is placed on the gutter. It prevents leaves and other large debris from entering the system.
When assembling the gutter with your own hands, place the mesh on the gutter. It will prevent foliage and branches from clogging the storm drain
Installing a grid will allow for less frequent maintenance of the system. This is especially true on tall buildings.
Homemade drain
Ready-made drainage systems are good, but not cheap. What to do if drainage needs to be done at the dacha and you need to spend a minimum for this? There are several very budget options. The first is to make a drain from plastic sewer pipes. Take pipes of large diameter (110 mm and more), good quality with a thick wall, cut them in half and use them as gutters. The same diameter or slightly smaller can be used as drain pipes. It’s more convenient to buy ready-made brackets, but in principle, you can make them yourself. For more information on how to make a drain with your own hands from sewer pipes, watch the video.
Even more a budget option- drainpipes made from plastic bottles. They cannot make a normal gutter, but the pipe funnels work normally.
How to install a plastic drain - installation according to instructions
Plastic elements have long been used to construct drainage systems. Contrary to popular belief about their unreliability, drains made of plastic are in many ways superior to traditional metal parts. In addition to good technical parameters, plastic components for drainage systems are also quite affordable, which makes them an extremely profitable purchase. This article will discuss plastic roof gutters and their features.
Device and equipment
For the production of plastic gutters, polyvinyl chloride is used - a polymer material obtained by thermoplastic processing. All components of drainage systems are made from this material.
Installation of plastic gutters is carried out using the following elements:
- Gutters. These elements are necessary to receive and transmit water flowing from the roof slopes to the water intake funnel. Plastic gutters differ from metal products in a wide variety of sizes, which allows you to choose the best option for a particular situation.
- Gutter coupling. The coupling allows you to connect individual parts of the gutter. This element is small in size, and its installation requires silicone sealant or a rubber gasket.
- Corner. The angles allow you to direct the plastic gutter in the desired direction. In construction, parts with a right bend angle are most often used, but if it is necessary to create a different angle, a non-standard option can be found on the market.
- Brackets. These elements are fasteners that support the gutter. The holders themselves are attached to the sheathing boards.
- Stubs. These parts of the drainage system allow you to block water from accessing the drain through the edge of the gutter, located on the other side of the funnel.
- Water intake funnel. This is an essential element of any drainage system, which collects water from the gutter and transfers it to the drain pipe. Visually, this part is a small trench that turns into a funnel.
- A drain pipe. This pipe is installed vertically and ensures that the liquid collected by the funnel is transferred to the storm drain.
- Drain pipe end. This element of the drainage system is necessary so that the flowing water slows down as it drains. The tip has a curved shape, due to which the speed of liquid movement is dampened.
- Brackets for drain pipe. The brackets are attached to the wall of the building at a certain pitch, after which a pipe is inserted into their outer rings.
When choosing plastic drainage elements, you need to remember that there are no strict standards regarding the size of parts. To ensure that plastic drainage pipes are compatible, it is worth purchasing a complete set from one manufacturer.
Advantages of plastic drainage
Plastic drainpipes have the following positive qualities:
- Completely resistant to corrosion. Like all polymers, polyvinyl chloride is completely resistant to oxidation, so it can be successfully used for collecting and transporting liquids.
- Light weight. Light weight is another quality common to all polymer products. Thanks to this quality, installation of plastic drainage can be carried out without additional reinforcement of the roof truss system.
- Low noise level. Of course, there will still be noise from falling and flowing water, but if we compare the acoustic properties of metal and plastic products, the latter will come out ahead by a significant margin.
- Easy to install. Plastic elements of drainage systems are very easy to work with, so you can easily install them yourself. In addition, the installation of plastic drainage is greatly simplified due to the low weight of polymer products.
- Low cost. Plastic drainage systems are much cheaper than metal ones, and there are much fewer problems with them.
- Long service life. Components made of polyvinyl chloride under normal operating conditions can easily last about 50 years without any complaints.
- Variety of colors. If necessary, you can easily select plastic parts that match the color of the existing exterior of the building.
- Possibility of self-adjustment. Even when installing a drain with a complex configuration, problems will not arise - if necessary, plastic parts can be easily cut with a hacksaw without losing their characteristics.
Disadvantages of plastic drains
Plastic has its negative qualities, which you need to know about before installing a plastic drain:
- Low mechanical strength. This is one of the most serious disadvantages of plastic products. A huge number of plastic drainage systems simply broke down as a result of heavy snowfall. If the region in which construction is taking place has a significant level of precipitation, then it would be better to choose more durable materials for arranging the drainage system.
- The need for preliminary drainage calculations. In order for the drainage system to operate normally, it must be designed and calculated before installation. Otherwise, the throughput of the structural elements may simply not be enough, and the entire system will have to be reinstalled using larger parts.
- High degree of thermal expansion. When exposed to high or low temperatures, the plastic changes in volume, which, if the elements are rigidly fastened, may well lead to their deformation. To avoid this phenomenon, plastic parts must be secured using the floating method or using rubber gaskets.
Installation of gutters and PVC pipes
In order for the drainage system to perform its functions efficiently, it must be properly installed. Naturally, before this, the building must have a rafter frame and sheathing protected by waterproofing material.
Installation of a plastic drainage system is as follows:
- First, you need to mark the gutter attachment points on the front board so that the slope is from 3 to 5 degrees per meter of drainage (to maintain the slope, you should use a cord);
- Next, the brackets are attached, and they need to be installed so that the overhang of the slope is exactly in the middle of the gutter - this placement will protect the drainage system from snow;
- The installation process must be started from the point where the funnel will be located, measuring 15 cm in each direction and installing brackets at the resulting points;
- All brackets, except the first ones, are installed in increments of about 50 cm, and installation is carried out towards the funnel;
- A funnel is installed on the brackets, after which you can begin installing the gutter, having previously adjusted it to the required dimensions;
- When installing the gutter, it is necessary to use sealant or rubber connecting elements;
- The brackets necessary for fixing the drain pipe are attached to the wall vertically in increments of one meter;
- Next, a drain pipe is mounted, which must first be attached to the funnel, adding the necessary part with separate parts of pipes fastened with couplings;
- The lower part of the drain is equipped with a curved tip, the edge of which should be located at a distance of no more than 30 cm from the ground.
It is advisable to install PVC gutters at temperatures above +5 degrees. The fact is that at average temperatures the plastic will take its normal shape. It is also worth remembering that the dimensions of polymer parts change as a result of temperature changes - this must be compensated for by leaving small gaps when tightening screws or using special elements that provide such a gap. Some craftsmen even make drainage from plastic bottles, which is free.
Conclusion
Plastic drainage is a reliable and convenient system that, with high-quality selection of components, proper installation and normal operating conditions, can last for several decades.
Installing a plastic drain with your own hands
Problems with a constantly wet foundation and damp building walls are familiar firsthand to many owners of private cottages. The best option for solving problems of this kind is to install a plastic drainage system.
Features and stages of work on installing a plastic drain
Why should you choose plastic?
Of course, when purchasing and installing a gutter, every owner of a private home “cherishes the hope” of spending money once and not thinking about it again. excess moisture for many years.
In this regard, before purchasing a drainage structure, he must carry out comparative analysis gutters made from different materials. We will carry out the same analysis by comparing metal and plastic systems:
- almost all types of plastic drainage systems are distinguished by great structural diversity; they can have a rectangular, round or even shaped shape;
- when hitting plastic pipe(gutter, funnel) masses of water flow down almost silently (unlike a metal gutter);
- galvanized steel gutters even the most High Quality inferior to their plastic counterparts in such an important parameter as the period of trouble-free operation;
- the production of high-quality steel products is many times more expensive than the production of plastic structures;
- all discussions about the imaginary fragility of plastic drainage systems have no basis in evidence. Many years of experience in their use is a serious confirmation of the durability and reliability of plastic systems;
- Due to the low weight of the plastic structure, it is very easy to assemble and install. In addition, with this approach it is possible to reduce the load on the row structural elements building;
- The likelihood of a leak in the version with a plastic drain is very small. This is primarily due to the geometry of the plastic structural elements.
About preparatory work
A well-drafted project for future assembly and installation work is a good opportunity to reduce real costs. First of all, you should decide on two important points: the number of drainage pipes and the length of the hanging gutters of the system.
Based on these two parameters, you can calculate the number of other auxiliary elements, requiring installation. We are talking about drainage funnels, clamps and holder brackets, corner bends, plugs for gutters, and so on.
The diameter of gutters and pipes is usually selected based on two indicators - the roof area of the building and the approximate amount of precipitation falling in a given area (see special tables).
The number of necessary auxiliary parts will again depend on the area of the roof and its configuration (how many slopes). If we are dealing with a non-standard or complex roof, we should, among other things, take into account every break and angle. In the case of a very long roof (length), the drainage funnels of the gutters should be located at a distance of no more than 24 meters from each other.
About installation of gutters
Exists general recommendation for installing a gutter, ensure that the angle of 2 degrees is observed when installing the structure. In order to ensure a smooth system for draining moisture from the roof, we recommend using simple and reliable method. We install a pair of outer brackets with a pre-calculated interval, and place the remaining brackets along the rope with an interval of 60 centimeters and attach them to rafter system or front boards.
The uppermost ends of the gutters should be located three to four centimeters below the edges of the roof slopes. In this case, the snow mass will enter the drainage system without delay.
The outer edges of the gutters should be located lower than the inner ones, then if water overflows over the edge, it will not fall on the wall surface.
High-quality roof gutters should be installed in such a way that moisture collects in the middle of the gutters. For this purpose, special gaskets are used, which are placed under the bases of the brackets.
Installation of the gutter is carried out in the direction from the roof to the ground. There are two main ways to seal connections. IN in this case We are talking about permanent adhesive joints and rubber gaskets. Each of these options has its own advantages and disadvantages.
The joining of adjacent elements is made using understatements. Each assembly part must be inserted all the way. The option with rubber gaskets has a rather serious drawback - they will have to be changed over time (this is inevitable). Self-replacement repairing a failed drainage system part is a rather difficult and time-consuming process.
The standard length of plastic gutters for roof gutters is three or four meters.
It is known that cutting plastic is very simple work. However, try to keep the number of connections to a minimum. Each of the burrs formed during the work should be removed with a knife or file (thus, the contact of the joints is improved).
If you have a small one-story house and you have chosen the adhesive type of connections, the gutter can be assembled on the ground.
An important point: installation of gutters is difficult without outside help.
About the installation of funnels
Water inlet funnels are attached to the gutter or to the wall surface (in the second case, the funnel simultaneously plays the role of an additional support and connecting part of the gutter). In the option of hanging the water collector on the gutter, it is necessary to make a drain hole in the wall of the gutter.
Water collectors are one of the key components of the entire system. If leaves or other debris gets inside the funnel, it can cause the passage to be blocked. The result of this is often the rupture of drainage pipes. In this regard, it would not be superfluous to equip the funnels with “options” for collecting garbage (we are talking about nets and spiders).
About pipe installation
Most often, when installing a drainage pipe to a wall, an elbow with an angle of 35 degrees is used. The use of such an elbow ensures smooth water flow in the future.
The structure is fastened to the wall using two (or more) clamp holders (the interval between clamps is 2 meters). The recommended interval between the drain and the wall surface is 3 centimeters. This figure can be used as a guide when cutting sections of pipes connecting elbows (here it is necessary to take into account the length of the connecting sections inside and the length of the fittings on the outside).
Water jets are attached to the lower ends of the pipes, which are necessary to drain water flows from the walls.
If we are talking about installing a drainage system in a house where people will live on a permanent basis, it is worth investing in a heating cable. This option is a good way to prevent ice in pipes, catch basins and drain funnels.
Video: Installation of PVC gutters
The drainage system is a structure that designed for controlled drainage of sediments from the roof surface, and to protect the blind area and the buried part of the building (foundation, basement) from moisture in order to prevent or minimize the destruction of relevant building and finishing materials.
To construct a drainage system, plastic gutters are mainly used, but due to the higher cost of the former, many people prefer PVC products.
Now let's talk about this in more detail.
The PVC gutter is product made of hard, impact-resistant plastic. For the production of system elements, plasticized and unplasticized polyvinyl chlorides are used with the use of various additives: coloring pigments, wear-resistant plasticizers, stabilizers and UV additives.
Manufacturers They produce samples in a variety of colors, which makes it easy to match the gutters to the color of the roof. Products are painted in bulk so that small scratches and defects on the surface are not too noticeable.
If Only the top layer is painted, which means the drain is of poor quality and was most likely made in artisanal conditions.
Plastic drainage systems have the following advantages:
- moisture resistance. Since the function of the system involves direct contact with water, it should be noted that plastic is absolutely not afraid of moisture;
- light weight. Using PVC structures the load on the cornice of the building is reduced;
- durability to high and low temperatures(from -40 to +50 degrees);
- UV protection. If the drain is made of good quality plastic, it is not afraid of exposure to UV rays, so the product will retain its appearance for a long time;
- Plastic roof gutters easy to cut, are not afraid of scratches and minor accidental impacts;
- installed on and without cornices roofing slabs, and installation can be carried out in almost any temperature conditions, down to -20 degrees;
- low cost. PVC is a material that is easy to manufacture and process, which has a positive effect on the price of finished products. Examples of manufacturing companies - and.
Disadvantages of plastic systems:
- susceptibility to mechanical damage. This circumstance does not allow the installation of such structures on high-rise buildings. PVC systems can only be installed on private houses;
- unsuitable for repair. A damaged part cannot be repaired;
- a drainage system made of plastic with rubber seals requires periodic replacement, which is why it is necessary to disassemble and assemble structural elements;
- large temperature expansion range. On a 10-meter-long section with a temperature difference of 20 degrees, the plastic increases to 1.5 cm.
Plastic roof gutters from docke
Types of element
Drainage systems may have different shape:
- Round.
- Rectangular.
- Square.
- Trapezoid shape.
The first option is considered classic and occurs more often than others. There are no stiffening ribs on such gutters, so their installation is carried out using special clamps, which provide more reliable fastening of the elements to each other.
Rectangular samples are very similar to sidewalk ones drainage drains. They are equipped with several stiffening ribs and are quite large in volume, which makes it possible to equip a system capable of draining a large number of Wastewater. Rectangular and square pipes They are mainly used for closed drainage systems. Such structures are installed in the roof and equipped with drainage funnels.
Structural components of PVC drainage
To install a plastic drainage system, manufacturers produce various components that allow you to build a structure of any configuration.
Plastic gutter
They are channels for collecting liquid, which are located along the edges of the roof and receive water flowing from the roof, directing it into the water intake funnel.
also have accessories:
- coupling. This element is designed to connect individual parts of the gutter to each other.
- Corner. Used to connect gutters at turning points. The most common designs have a 90 degree angle, but other options are also found.
- bracket. It is a plastic hook for fixing the gutter. Attached to front board, after which a drain is inserted into it.
- Stub. Used in places where the gutter is not connected to other parts of the system. Places on the end of the element and limits unorganized water flow.
Water intake funnel
This is the most important part of the drainage system. It receives the liquid flowing down the gutter, which then enters the drain pipe. In appearance, this element looks like a short gutter with a funnel-shaped end.
A drain pipe
It is a vertical pipe that is connected to a funnel. This element is designed to provide directional drainage of liquid and divert flows away from the building.
NOTE!
Closer to the surface of the earth, drain pipes are usually have a bend in the opposite direction from the wall, through which liquid flows through storm water inlets into a storm sewer or drainage system.
Drain pipe end
A part that reduces the speed of water falling. The tip is bent so that the liquid flows smoothly from the roof.
Drain pipe clamp
A ring-shaped fastener with which the pipe is mounted on the wall. In fact, this element performs the functions of a bracket and is often even sold under this name along with other connecting parts.
Drainage system design
Which gutter is better: plastic or metal?
To highlight distinctive features both options, you should compare their characteristics according to several main parameters:
- Weight. Plastic is much lighter than any type of metal, so in this respect it is superior to its metal counterpart, which requires the use of reinforced brackets for mounting.
- Durability and impact resistance. These properties are, of course, to a greater extent inherent in metal products, because plastic, no matter what it is, is not able to withstand significant mechanical stress.
- Susceptibility to corrosion. Plastic products Corrosion is absolutely not dangerous, whereas they are subject to the negative influence of water. But aluminum, metal-plastic and zinc products protected from moisture, but they are more expensive than other analogues.
- Tightness. Plastic connections are more airtight than metal ones and do not leak, which allows them to be characterized as more efficient.
- Durability. The warranty on plastic products is 25 years, steel analogues last 15-20 years, and polymer-coated samples last 50-60 years.
- Temperature resistance. The operating temperature of plastic is -40 to +50 degrees, and metal from -50 to 120, which allows the use metal systems in the conditions of the far north.
Based on the above parameters, it is difficult to say about the clear advantage of one material over another, so the choice in favor of one or another option depends, perhaps, to a greater extent on the situation, the preferences of the owner and his material capabilities.
Metal drain
Attaching the drainage system to the roof
Gutters are attached to the roof, the specific installation of which depends on the conditions under which the drainage system is installed (on a house under construction or in operation), as well as on the characteristics of the roof.
- Fastening to the front board. This is the simplest method, but it is only possible if there is access to the rafter system. Therefore, this option is well suited for “new construction”.
- Fixation to rafters. If there is no frontal board in the roof structure, combined holders are used, which are equipped with “extensions” attached to the rafters.
- Installation on "crutches". This method is used when it is not possible to use the previous two. In this case, the metal parts can be attached to the sheathing or to the wall.
To ensure that the parts are placed correctly, It is recommended to secure the outer brackets first, and then everyone else.
Attaching brackets
Do-it-yourself drainage system installation
Installation of a plastic drain is carried out in several stages:
- The gutter hooks are attached using one of the methods described above. The distance between the elements is 0.6-0.9 m. In order for water to drain well, a slope of at least 0.5 cm per linear meter should be provided.
- The gutter funnel is installed. The number of these elements depends on the area of the roof slope and the length of the gutter. One funnel can serve up to 120 m2 of roofing and up to 10 linear meters drain.
- Plugs are mounted, which are attached to the edges of the gutter that do not fit with other structural parts.
- The gutter is installed. The upper outer edge of this element should be located no closer than 2.5 cm from the roof slope line. It is also necessary that the inner edge of the drain rises 0.6 cm above the inner edge, which will prevent water from entering the facade of the building during heavy rains.
- Connecting and corner elements are mounted. The distance between the drain sections when connecting should be 3-4 mm.
- Drain pipe being installed. Brackets are attached to the wall at a distance of 1 m from each other (but not less than 2 pieces per pipe). The upper elbow, the drain pipe and the drain elbow are connected to each other, after which the structure is attached to the funnel.

Gutter marking
When installing the system, it is also advisable to follow the instructions from the manufacturer, but in any case, all elements of the system must be securely fastened, which will reduce the risk of emergency situations when operating the drain.

In contact with
Some homeowners are wary of using plastic gutters. The opinion has become firmly established in the minds of consumers that products made of plastic are less reliable than those made of metal. This material is perceived as synonymous with unreliability, fragility, and fragility. However, this statement has long been untrue, because modern components for assembling a system for draining melt and rainwater from a roof made of polyvinyl chloride are much superior to their metal counterparts in terms of service life, tightness and quality. In this article we will compare plastic gutters with products made from other materials, discuss the positive aspects and installation rules.
Device and equipment
Modern plastic gutters are made from polyvinyl chloride, a thermoplastic polymer that is a product of petroleum refining. To ensure water drainage from the roof, manufacturers offer a wide range of components, which can be assembled to create any configuration. roofs are used the following elements made of plastic:
- Gutters. They take the liquid flowing from the slopes and transfer it to the collection point in the water intake funnel. Such gutters, unlike metal ones, have a wider choice of gutter section sizes.
- Gutter coupling. This is the part necessary to connect the gutter sections together. The coupling has a shortened length and is mounted using silicone sealant or rubber seal.
- Gutter angle. This drainage element is used to give the gutter the right direction. The most open parts have an angle of 90 degrees, however, some manufacturers produce others.
- Gutter bracket. A plastic holder in the form of a hook, which is attached to the front board and a gutter is inserted into it.
- Gutter plug. This is to make a plastic drain, which is put on the end of the gutter opposite the water inlet funnel to limit the unorganized flow of water.
- Water intake funnel. The most important element drains that collect water from the gutter and enter the drain pipe. Externally, this part looks like a short groove with a funnel-shaped process.
- Drain pipe. This is the name given to a vertically located pipe that connects to a funnel and ensures the transfer of water to the storm drain.
- Drain pipe end. A segment of pipe that reduces the speed at which water falls, bent so that water flows smoothly from the roof.
- Bracket for drain pipe. A fastening in the form of a ring, with the help of which the pipe is mounted on the wall.
Unlike metal gutters, plastic ones provide the opportunity to equip water drainage for any roof configuration. Installation is possible even if the angle between the slopes is not 90 degrees, since plastic products can be easily adjusted to size by cutting them with a regular hacksaw.
Pros of plastic drain
Plastic gutters are still used less frequently than metal ones. However, the use of high-quality material for their production makes it possible to increase new level efficiency of collecting and transferring water from roof slopes. To convince of the practicality of drainage systems made of polyvinyl chloride, it is enough to list their operational characteristics:
Note! The peculiarity of a plastic roof drain is that when the temperature changes, it changes its volume. This property often causes deformation of their polyvinyl chloride elements during the first frost if the installation was carried out without compensation parts.
