Installation of PVC gutters: step-by-step instructions with photos. Installation of a plastic drainage system: basic rules and recommendations Installation of a plastic drainage system yourself
Despite the merits metal structures, many homeowners prefer to install a plastic roof drain - a lightweight structure that is completely impervious to water. In order for such a drain to work properly, it is important to make the correct calculation of the system and follow the recommendations of specialists at the installation stage. In this case, using a system of plastic elements, you will be able to reliably protect the foundation and walls of the house from moisture.
You can install gutters from various materials:
- galvanized steel,
- copper,
- metal with polymer coating,
- plastic.
Plastic has certain advantages, especially in cases where the installation of the drain is done by hand:
- The low weight of the elements makes it easy to assemble individual units and lift them to a height.
- Plastic gutters and pipes can be cut using tools available to every DIYer.
- When cutting plastic elements, you do not need to use any special technologies, there is no risk of damage to coatings (as with polymer coatings), which can reduce corrosion resistance.
- Gutters, pipes and funnels made independently or purchased in a store are easily connected; using special compounds or fasteners, it is not difficult to ensure the joints are sealed.
- The plastic is absolutely impervious to moisture and is also resistant to other external factors, including ultraviolet radiation, chemically aggressive substances, temperature effects.
- The smooth surface of plastic gutters does not allow debris to linger as water flows.
- Planning to install plastic gutters, you can choose any color of the structures that matches the façade design.
- The price of plastic roof gutters is significantly lower compared to metal products.
Main elements of a drainage system
Before you begin installing plastic gutters with your own hands, it is important to prepare all the necessary components. Calculation required quantity materials are produced taking into account the dimensions and design of the house:
- complexity of the configuration (number of corners and protrusions),
- wall lengths,
- building height.
A plastic roof drain consists of certain elements:
Gutter
Gutters are channels for collecting liquid that rolls down the roof surface during rain or snowmelt. Their inclined position (slope towards the funnel) ensures drainage into the pipes without overflowing the gutters. Thanks to the installation of collecting gutters, water does not fall on the walls and soil near the house or, preventing premature destruction of structures.
Vertical pipes
Pipes provide directional drainage of water from gutters and drainage of flows away from the building. At or above the ground, drainpipes usually have a bend away from the wall that transports water through storm inlets into a drainage ditch or irrigation tank.
Vertical installed pipes fixed on the wall using special devices. In this regard, the low weight of plastic models is additional benefit. They are easier to attach and do not place additional load on vertical structures.
Plums
Drains (funnels) are connecting elements between gutters and pipes. The tightness of the joints ensures that there are no leaks. Drains are essentially splitters for connecting gutters and pipes.
Gutters and pipes are part of storm sewer which drains water away from the house Mounting accessories
Do-it-yourself installation of plastic roof gutters is done using special installation tools.
These include:
- connectors,
- clamps,
- brackets,
- plugs, etc.
Installation of plastic gutters
If you have chosen plastic gutters for your roof, you can install them yourself in two ways.
- For small areas one-story houses The drainage system can be assembled on the ground and only then lifted for installation in pre-mounted brackets. The technique is not suitable for houses above 1 floor and large area building, since the assembled large structure may be damaged during lifting.
- Gutter elements can be raised individually at roof level and assembled into a single system on site.
Plastic or metal fasteners are used for installation. The choice of material depends on the home owner's preferences and durability considerations. The installation location also matters.
- Gutters are attached to the roof rafters only using metal fasteners.
- On the frontal board, elements can be fixed with both plastic and metal.
Do-it-yourself gutters made from plastic pipes and gutters are installed according to certain rules.
We have material on our website about how to conduct. The work differs depending on the material of the blind area.
One of the arrangement options summer shower- this is the use of polycarbonate sheets for sheathing the frame. Construction instructions
Gutter heating
When making roof flashings with your own hands from plastic pipes, think about the feasibility of heating the system. Heating allows prevent icing of structures with changing temperatures in the off-season or during a thaw. Ice makes the elements heavier and increases the load on the fasteners; it can cause the destruction of the drain, especially plastic ones.
Effective protection against icing is heating cables, installed using special brackets inside the gutters.
- Resistive heaters heat up evenly and warm up the system's gutters.
- Self-regulating ones increase and maintain the temperature in certain areas. Such systems are more efficient and economical.
Heating can also be performed for drainpipes.
Gutters made from plastic bottles
Drain from plastic bottles It’s not difficult to do it yourself. From an aesthetic point of view, such a system will be inferior to those made from purchased elements and even from plastic sewer pipes However, in terms of functionality, homemade gutters meet all the requirements.
According to the masters, the best way Bottles with a capacity of 2 liters are suitable for these purposes, although 1.5 liter containers can also be used. The neck and bottom are cut so that an even cylinder of the maximum possible length is formed. After this, the cylinders are cut in half and overlapped. Fixation is ensured using pieces of wire or a stapler. For vertical pipelines, the bottles are cut so that the cylinders have a narrowing on one side. By inserting the cylinders into each other using the narrowed sides, a pipe is obtained. Funnels can be made from cut necks. Gutters made from plastic bottles are attached to building elements using wire rings.
Horizontal gutters can be installed on a wooden board pre-attached to the roof for added rigidity.
Let's look at how installation is carried out in the article. drainage system. What elements does it consist of, and what must be taken into account when assembling it. After reading the information, you can easily talk with the contractor, plus optimize the costs of purchasing a drainage system from the roof of your own home.

What does the drainage system consist of?
It includes two main elements:
gutters, also known as trays, that are installed on the eaves of the roof, and their main task is to collect rain or melt water from stingrays;
the pipes into which water flows from the trays are located vertically, and their task is to discharge water into the storm drain.
There are additional elements:
funnels through which water flows from the trays into the pipes:
bends for assembling pipes, if it is necessary to lay them along architectural protrusions on the building;
brackets for fastening trays;
clamps for attaching pipes to walls;
plugs for closing the rear ends of the trays.

The sequence of installation of the drainage system
The first step is to install the gutters. They are attached to brackets, which are attached either to the first element of the sheathing, or to the rafter legs, or to front board. The best option- first. But it can only be carried out if the roofing material is rafter system not yet installed. If the roof is already covered, then the brackets are attached according to the last two options.

Attaching brackets to sheathing
For this purpose, brackets with a long leg are used. They just bend it back required length, applied to the sheathing and secured to it with self-tapping screws through the holes made.
Bracket with long leg Source www.braersnab.ru
It is important to strictly adhere to two parameters during installation:
distances between fasteners;
distance from the middle of the hook to the edge of the roof overhang.
The last parameter should vary in the range of 30-40 mm. This is done so that the water coming off the roof gets into the middle of the gutter. To avoid overflowing over the edges of the trays and splashing water.

Attaching to rafter legs
If the roofing material has already been laid, then one of the options for attaching the brackets is to the rafters. For this, the same fasteners with a long leg are used, only they have it rotated 90°. This way it is simply more convenient to carry out the fastening.
Fastening to the front board
On one of top photos It has already been shown how to attach the bracket fasteners to the front board. For this purpose, short products without legs are used, but with a stand in which mounting holes are made.
It is necessary to indicate that today manufacturers offer various models, which mainly differ from each other in the method of fastening. The photo below shows an option where the fastening element is a bar with a full-length groove. It is attached to the front board, and the brackets themselves are inserted into the grooves.

Other options
If it is not possible to install the brackets according to the options described above, then you can attach them to the roof overhang. For this purpose, brackets with a long leg are used, which bends to the required angle and length. The photo below shows this installation option.

On our website you can find contacts construction companies, which offer turnkey roofing work of any complexity. You can communicate directly with representatives by visiting the “Low-Rise Country” exhibition of houses.
Rules and sequence for assembling gutters
The main task of the work manufacturer is to fasten the gutters of the drainage system at a slight angle of 3-7°, since the drainage system is a gravity flow system. Therefore, on one side of the slope the bracket is installed closer to the roof eaves, and on the other side opposite side slope lower to form a slope. Then a thread is pulled between the two fasteners, along which other brackets are installed in increments of 50-60 cm.
All that remains is to lay and secure the gutters to the fasteners. The main thing is that the laying is done overlapping the edges of the trays, this is when the edge of the upper tray is laid over the edge of the lower gutter. In this way, problems of leaks at joints are solved. To reduce the possibility of leaks, the joints are treated with silicone sealant.
Pipe installation
The second stage of drainage installation is the installation of vertical pipes. There are strict standards that determine installation locations pipe elements. This distance between them is 12 m. For example, if the length of the façade of a building is 12, then one pipe structure is mounted on its surface. If the length is longer given value, but less than 24 m, then two risers are installed.
Pipes are fastened to the walls of the house with clamps in increments of 1.8 m. If the height of the house exceeds 10 m, then the installation spacing is reduced to 1.5 m. The clamps themselves are fastened with self-tapping screws through plastic dowels. The main requirement is strict vertical installation. Therefore, at the installation site, first determine the vertical along the wall using a plumb line. Then, measuring the installation step, they make notes in which they drill holes for the dowels.
Installation of a drain pipe riser Source krovlyakryshi.ru
The assembly of pipes, the standard length of which is 3 m, is carried out using the socket connection method. This is when one side of the pipe has a larger diameter than the opposite. That is, the pipes are inserted into one another. In this case, pipes with a large diameter are installed upward. To completely seal the joint, they are treated with silicone sealant.
Pipes and trays are connected to each other by funnels. A drain is mounted at the bottom of the pipe riser - this is a branch at an angle of 45°. Here it is necessary to take into account that the lower edge of the drain should be at a distance of 25 cm from the surface of the soil or blind area.
An important point is the installation of a drain (riser) at the eaves of the roof, where bends are used. Because the overhang roofing material It is located at a distance of 30-50 cm from the wall surface. This means that in order to connect the funnel to the pipe riser, two bends at 45° are needed. If the roof overhang is large, then a piece of pipe is installed at an angle between the bends.

How to choose the right drainage system
Just going to the store and buying a drainage system without deciding on its parameters is wasted money. There are certain standards regarding the size of the roof, or more precisely, the area of the slope from which water will be collected into the drainage system. And what larger area, the larger the dimensions of the trays and pipes should be in terms of their diameter. Therefore, before proceeding with the installation of the drainage system, it is necessary to accurately select its dimensions in accordance with the area of the roof slope.
If the area of the roof slope does not exceed 50 m², then gutters with a width of 100 mm and pipes with a diameter of 75 mm are installed in the drainage system.
The area is within 50-100 m², gutters are used - 125 mm, pipes 87-100 mm.
The slope area is more than 100 m², gutters 150-200 mm, pipes 120-150 mm.

Heating cable in a drainage system
Ice and snow inside the drainage system create a blockage (plugs) that prevent melted water from draining. As a result, it overflows over the edges of the trays, forming icicles. Everyone knows how dangerous they are. In addition, a large amount of ice and snow inside the trays means there is a high probability of collapse of the entire structure or deformation of its elements. To prevent this from happening, a heating cable is installed in the drain. This is the conductor electric current, which releases thermal energy.
Heating cable inside the gutter Source rooms-styling.com
The heating cable is installed after installing the roof drain. It is simply laid inside the gutters (along) and lowered inside the pipe risers. It is secured in trays with special clamps made either of stainless steel, or galvanized, or plastic.
In addition to the cable itself, the kit includes a power supply and a thermostat. The first supplies the current of the required voltage and strength, the second regulates the temperature of the cable depending on weather conditions. For example, if the temperature outside is -5C, then the cable does not heat up much. If the temperature drops below, the current inside the conductor increases, which increases heat transfer. This is what the thermostat controls.
It should be added that the thermostat itself does not determine the temperature. To do this, sensors are added to the system: either temperature or humidity.
Most often, the heating cable is installed not only inside trays and pipes. They cover part of the roof, and more precisely the area overhang. Here the conductor is laid in a snake pattern and secured to the roofing material with special clamps. This is clearly visible in the photo below. In this case, it is necessary to indicate that the heating cable both inside the drain and on the overhang is one system with one power supply and thermostat.

Varieties of modern drainage systems by material of manufacture
Traditionally, gutter systems were made of galvanized steel. And today this material has not left the market. They simply began to coat the galvanized drain with paint, thereby matching it to the color of the roofing material, creating a unified design for the house. Plus, it became possible to extend the service life due to an additional protective layer.
Today, manufacturers offer galvanized gutters and polymer coating. In this case, the polymer coating is applied both on the outside of the galvanized sheet and on the inside. This means better protection and a huge variety of colors, unlimited in any way.
Plastic drainage structure Source rooms-styling.com
Plastic gutters are the most popular today. They are made from polyvinyl chloride (PVC). But this material is not used in its pure form, because it itself becomes brittle when low temperatures. Additives are added to it, which increase the strength of the polymer, so PVC gutters are not afraid of temperature changes and sun rays. And the biggest plus is that plastic is the cheapest material.
The modern market today offers drainage systems made of copper or stainless steel.

Generalization on the topic
Installing roof gutters is a serious process. The main task of the work manufacturer is to correctly select its elements in accordance with the area of the roof slope, correctly set the angle of inclination of the gutters and correctly fasten the structural elements.
Nowadays, in order to ensure the removal of precipitation, drainage systems made of plastic are most often used, because the functioning of the entire system depends on how correctly the material is chosen.
Due to it, the walls and foundation of the house are preserved, and moisture does not penetrate into the living space.
Plastic drainage system
Advantages and disadvantages
The principle of operation of the drain is that rain and melt water accumulates in the gutters, after which it flows down the drainpipes into the storage capacity, drainage, etc.
The standard design includes the following elements:
As already indicated, the most common material used in the manufacture modular designs, is plastic.
But you can also find metal drains and those made of galvanized steel.
Metal drainage system
Considering that the plastic drainage system is in greatest demand, I would like to consider its advantages and disadvantages.
- even for a person who has no experience in this matter, installation does not present any difficulty;
- low weight of components;
- resistance to corrosion processes, low temperatures;
- high degree of sound absorption;
- relatively long term operation;
- easy care;
- large color range of products.
Installation of a PVC drainage system
By the way, the installation of a plastic drainage system is described in detail in the instructions from the manufacturer.
Like any structure, it also has some disadvantages, expressed in the insufficient elasticity of the material, which sometimes leads to deformation of the elements.
Also, some types of plastic can degrade when exposed to ultraviolet rays.
Do not forget that you must always take into account the features of the roof. For example, if this natural tiles, then plastic pipes are unlikely to be suitable.
As for the price, plastic costs 3 times less than metal, but the service life of such a system is a maximum of 15-20 years.
Cost of drainage PVC systems always depends on factors such as:
- total roof area;
- complexity of the roof;
- number of elements included;
- color;
- manufacturer, and, of course, the complexity of installation.
On average, the price for drainpipes starts from 120 rubles/m, and for gutters at least 100 rubles.
Basic installation rules
Plastic drainage systems are installed on buildings in accordance with certain rules. This helps you avoid the most common mistakes.
So, correct device roof drainage system:
Calculation of drainage installation
- strict adherence to temperature conditions during installation - for working with plastic optimal temperature air is +5 degrees Celsius;
- fastening the gutter with a slope - for PVC products it should be 3-5 mm per meter. The maximum distance between storm drains is 24 m;
- equal distance between gutter holders;
- the outermost part of the roof should be 1/3-1/2 of the gutter;
- use only a tool recommended by the manufacturer (metal saw or hacksaw) for cutting material, and metal scissors for making holes;
- installation of holders every 2 m from each other, compliance optimal distance pipes to the wall 3-8 cm.
The elements are connected using glue, latches/clamps, and rubber seals. It is imperative to take into account the gap to compensate for linear expansion.
Step-by-step installation of a drainage system
To do everything yourself and ensure proper operation of the system, you need to follow a clear action plan.
Stage No. 1 - installation of water intake funnels.
To do this, you first need to calculate the number of drainpipes and decide on their locations.
Funnels are installed where the gutters will be located; they can also serve as a gutter connector; in this case, glue or rubber seals are used to seal the seams.
Directly to roofing structure they are attached using brackets.
Before installing the gutters, holes must be made in the places where the water intake funnels are installed. First you draw the outline, cut it out with a hacksaw and sand the edges.
Installation of water inlets
Stage No. 2 - installation of brackets.
According to the instructions, the holders are fixed at a certain distance (50-60 cm).
It is imperative to ensure a slight slope of the gutter towards the funnel, it should be at least 2-3 mm.
For accuracy, you can install the bracket at the highest point, then tighten the cord and fasten the remaining elements along it.
It is worth noting that if you are attaching the holders to the wind board, then you can use plastic holders, but if you are attaching them to the rafters, then metal ones are needed.
Stage No. 3 - installation of the gutter.
The gutters are neatly placed into the installed brackets.
First, insert one edge into the latch, the one located on the edge of the holder, then press until the structure snaps into place.
Used for hermetic connection adhesive compositions, solders, connecting elements.
To avoid “overflowing” of water during heavy rains, the plastic gutter, namely its edge, when installed, must be below the continuation line of the roof.
Stage No. 4 - installation of a drip.
This element is needed so that water can freely escape from under the roof space.
Thus, melting and rainwater sent to drainpipes.
Mounting of the drip is carried out to rafter leg, it should extend 1.5-2 cm inside the gutter.
By the way, the corners are attached to the gutters in those places where there is a need to go around the protruding façade parts or the corner of the building.
After this, plugs are installed at the ends.
Installation of drip
Stage No. 5 - installation of drainpipes and assembly of the entire system.
Plastic pipes descend from each funnel from top to bottom.
They should be fixed at a distance of 3-8 cm from the wall.
Then, using couplings, it all comes together into a single unit.
Every 1-2 m the pipes are fixed with clamps.
Installation of drainpipes
Stage No. 6-7 - tees and drain.
If necessary, pipe splitters are installed at the last stages of installation.
As for the drain, there should be a distance of less than 30 cm between it and the ground.
If you plan to install a linear drainage system, then 15 cm will be enough.
Installation of tee and drain
Assessing all the stages of installing gutters, we can say that for this you will need tools such as:
- roulette;
- simple pencil;
- ruler and cord;
- hammer and screwdriver;
- hacksaw.
Don't forget the most important rule that installation work In no case should work be carried out with plastic products at air temperatures below +5 degrees Celsius.
This may cause the elements to crack when cutting or fastening them.
By the way, it is also not advisable to store plastic gutters in the open sun in their packaging.
Plastic drainage system - the best choice for your home
If you have seriously decided to start arranging a drainage system from the roof of your house, then after you have installed it yourself, it will not be a bad idea to learn about measures to prevent its contamination, icing and overflow.
Strictly following the instructions will help you avoid unpleasant situations.

The purpose of the roof over the house does not need to be explained. One of the functions is to protect the attic or attic from precipitation, i.e. from water leakage. But, flowing down the roof slopes, water inevitably ends up on the walls and foundation. As a result, the load-bearing elements of the building structure very quickly collapse.
You can avoid the destructive effects of water by installing a roof drainage system. Before we begin the master class on installing gutters, a little theory.
Types of drainage systems
The drainage system has two classification criteria that determine its installation technology:
1. According to the manufacturing method - homemade, industrial.
Handicraft production, i.e. homemade roof drain. This system is supported by facts such as the ability to make a beautiful and unusual drain with your own hands. Making a homemade system does not involve significant costs. In addition, it can be mounted according to a user-friendly scheme. The absolute lack of necessity constant maintenance, since gutters are usually made of galvanized steel, which quickly rots. Among the shortcomings are the difficulty of joining individual elements and mediocre appearance.
Factory production (factory). This method involves maintaining all standards and parameters. That is, if necessary, you can dock without problems various elements from different supplies from the same manufacturer.
2. According to the material used - plastic, metal.
According to the installation method, there are adhesive systems (installation occurs using glue) and adhesive-free systems (installation using rubber seals).
Advantages of plastic gutters:
- immunity to ultraviolet radiation. A high-quality plastic drainage system will not fade during its entire service life;
- not subject to corrosion;
- The adhesive system does not require maintenance, as the " cold welding» during which the connection of elements occurs at the molecular level;
- strength;
- light weight;
- worker temperature regime-40°С +70°С;
- ease of installation;
- availability of different colors;
- A wide variety of components allows you to create a drainage system of the desired configuration, which makes it indispensable for installation on broken roofs.
Disadvantages of PVC gutters:
- plastic may break due to mechanical stress. Therefore, such systems cannot be installed on high-rise buildings. A plastic drainage system is installed only on a low-rise private house;
- unsuitable for repair. A destroyed element cannot be restored;
- a plastic drainage system with sealing rubber bands requires periodic replacement of seals, which entails disassembling/assembling elements;
- high coefficient of linear expansion.
Drainage system from metal profile has several varieties: galvanized, copper, galvanized with polymer coating (painted). The main difference between them: cost and duration of operation. Appearance shown in the photo.
Advantages of metal gutters:
- strength;
- reliability;
- withstand significant snow loads and other environmental influences;
- do not support combustion;
- operating temperature -60°С +130°С;
- dimensional stability.
Disadvantages of metal gutters:
- high price;
- significant weight of the entire system;
- complexity of installation;
- small selection of colors;
- the appearance of rust when the protective layer is damaged (exception is a copper drainage system);
- a small number of elements makes it suitable only for installation on roofs with angles of 90°.
It is difficult to answer unequivocally which drainage system is better, plastic or metal, it all depends on the specific operating conditions and other factors. In any case, the choice of a drainage system should be based on quality indicators, not price.
From the perspective of this classification, we will consider how to properly install a drainage system with your own hands.
Installation of a drainage system - instructions
Like any construction process, the technology for installing gutters includes the selection of a system, material and calculations.
There are several options for drainage systems depending on their bandwidth. For example, 100/75, 125/90, 150/110. This marking shows the ratio of the diameter of the pipe and the gutter. Clearly round system 125/100 and square section- on the picture.
Advice. Each manufacturer has its own sizes of gutters and pipes. Their configuration is also different. Therefore, do not even try to connect systems from different manufacturers.
Such a variety of systems is necessary so that each user can choose the one that suits his needs.
Choosing a drainage system
To choose the right water drainage system you need:
- get acquainted with the maximum precipitation level in your region;
- calculate the area of the slope (S). Not all of them, but the largest in size. It is its size that will determine the choice of gutter
S = (A+B/2) x C
Nuance. For flat roofs(the slope angle does not exceed 10°) the formula takes the form
S = A x C
Based on these measurements, select the desired system in the table.
Once the system is selected, you need to determine the type and calculate the amount of materials. To do this, we will prepare drawings or plane diagrams with dimensions. They will simplify the calculation and then installation of the drainage system.
Calculation of the drainage system
Let us illustrate with the example of a house how to calculate the amount of materials for installing a drainage system.
Gutter - semicircular (semicircular cross-section) and rectangular ( rectangular section).
Designed to collect precipitation (rain and melt water) from the roof.
The length of the gutter is 3-4 m. It is secured with hooks and brackets, which are installed in increments of 60-90 cm, ensuring a slope of the gutter of at least 1 cm for every 3-4 meters.
Their number in linear meters is equal to the perimeter of the roof base. That is, the length of all surfaces on which the gutter will be mounted. Gutter sizes - sold individually in 3 and 4 m.p.
For a house the size of our example, you will need 3-meter gutters - 10 pcs. 4 meter - 1 pc.
Nuance. Round all dimensions to the whole length of the gutter. The fewer connections, the simpler, more reliable and cheaper the installation will be.
Gutter angles (external (external) and internal, 90 and 135 degrees).
The corner gutter is designed to change the direction (distribution) of water flows. Installation method: mounted on the external and internal corners of the roof.
We will need 4 external corners and 2 internal ones, all with an angle of 90 degrees.
If a house or cottage has sharp or obtuse corners, you need to choose the system in which such corners exist.
Advice. Various angles can be made from a plastic gutter by cutting out part of the gutter and connecting the halves at the desired angle. The parts are connected using glue - cold welding.
Gutters, connectors, gutter caps.
For our example - 4 funnels, 2 plugs. There can be 5 or 17 connectors, depending on the installation features of a particular system. In most gutter systems, the corners are attached directly to the gutter. But in some - using a connector.
In drainage systems where installation is carried out using glue, you need to use conventional connectors and compensation ones.
Compensation is installed when the roof length is more than 8 m.p. Its installation is carried out without the use of glue. This connector is designed to compensate for the linear expansion of the gutter during heating/cooling. For our example, 4 regular connectors and one expansion connector would be needed.
Advice. One funnel receives water from 10 m.p. gutters. If the wall is longer, you need to install two funnels. In our example, we did just that. In this case, the distance between two adjacent funnels cannot exceed 20 lm.
Gutter fastening hooks.
Hooks can be long or short. The first ones are designed to hang the gutter on the rafters and are attached before installing the roofing material. The second (short) ones are used to attach the gutter to the front board; accordingly, installation on finished roof, i.e. covered with roofing material.
The gutter fastening hook is installed at intervals of 60 cm. In this case, installation near corners, funnels, plugs and at joints is mandatory. In our example there are 68 hooks.
Drainpipes (for vertical drainage), pipe fastenings/brackets.
The pipe can be round or rectangular. Designed for vertical water flow.
The pipe bracket is designed for attaching the pipe to the wall. According to the installation method, they distinguish between “on stone” (for fixing on brick, stone or concrete wall. Fixation using hardware) and “on wood” (for fixing to wooden walls(timber, log, OSB). Fixation using self-tapping screws).
The number of pipes is determined by the number of funnels. In our example, there are 4 funnels, which means there are also 4 pipe installation locations. their length is equal to the total length of all walls along which installation is planned. Pipes are also sold in lengths of 3 and 4 m. Should be rounded to big side, since joints on the pipe are also undesirable. Those. if your house height is 3.5 m, you need to buy a 4 m pipe. 0.5 will go to waste or for other needs.
Pipe fasteners are installed every meter. At the same time, their installation near the knees is mandatory.
Pipe elbow, drain (drain elbow).
If the structure of the house is similar to that shown in the photo, then for each riser (we have 4 of them) you need two universal elbows (total 8) and one drain (total 4).
The distance L is measured as shown in the figure.
Material prepared for the website www.site
Nuance. makes some adjustments to the calculation of the drainage system. The height of the attic wall affects the number and installation of gutters. The diagrams below show what needs to be taken into account when calculating.
Installation of a plastic (PVC) drainage system
1. Installation of drainage funnels (roofing, storm drains, water inlet) on the roof.
The gutter fastening hooks closest to the funnel are installed at a distance of 2 cm from it. They serve as holders.
Advice. The angle of inclination relative to the funnel is 2° or 3-4 mm. by 1 m. It is convenient to check the slope using a nylon thread.
With a wall length of 10 to 20 meters, it is more advisable to install the gutter in the following ways:
- Simple slope (straight) - the funnel is installed at the end of the slope.
- Double slope: “from the middle” or “towards the middle”.
In the first case, the middle gutter is at the highest point, and the water moves to the funnels located at the corners of the building. In the second case, the two outer gutters are at the highest point and the water moves to the funnel located in the middle between them. If the length of the gutter exceeds 22 meters, three funnels or a more powerful system are installed.
3. Installation of a regular and compensation gutter connector (if necessary).
Gutter connectors are installed between the brackets. At an equal distance from them.
4. Cut the gutter into pieces of the required length. It is advisable to clean the cut area.
5. Connection of gutters with a funnel. The gutter is placed on brackets adjacent to the funnel, taking into account the linear expansion of the plastic.
The hole for the funnel can be drilled in the desired location of the gutter using a crown.
Some manufacturers mark funnels in such a way as to simplify installation. That is, the temperature scale is indicated on the side of the funnel. After checking the temperature outside, the gutter is installed at the desired level.
In adhesive systems, the funnel is one of the elements for which no glue is used during installation.
If provided, a sealing rubber is installed at the junction of the gutter and funnel.
When laying the gutter, the connector must be coated with glue or the joint must be sealed with an elastic band.
The expansion connector is installed without the use of glue.
Nuance. So that water flows in a given direction at the end drain pipe It’s better to make a “tear drop”.
7. Installation of corners and plugs for the gutter is carried out according to the same scheme.
Both the corner and the plug are mounted using glue or rubber seals.
8. Fastening clamps and installing drainpipes.
At the calculated distance, holes are drilled for fastening the clamp.
Pipe installation begins with installing an elbow (if necessary) or pipe into the funnel.
Glue or rubber compressor required.
Nuance. The lower pipe fits into the upper pipe with a gap of 2 mm. (linear expansion compensation).
The pipe is attached to the wall using a clamp. Which is installed in pre-drilled holes.
If necessary, a system of splitters (tees) is installed.
The ebb tide must be installed so that the water from it does not destroy the foundation of the house. For example, low tide diverts water into a canal drainage system or directly into a drainage well.

Installation of a metal drainage system
Step-by-step guide, instructions for installing gutters for a roof made of metal profiles with your own hands.
1. Installation of two extreme brackets.
They can be installed on the rafter system or on cornice strip(frontal).
Advice. For normal outflow of water from the roof, the angle of inclination of the gutter towards the funnel should be 3-4 mm per 1.m.
The bracket is mounted using three self-tapping screws.
When the wall length is more than 10 m, a simple (straight) slope is performed. If the length is more than 10 m - double.
2. Open the gutters.
The saw area is cleaned with a file.
Advice. The saw moves in the “away” direction.
3. Cutting a hole for the funnel.
Advice. The diameter of the hole should be slightly larger than the diameter of the funnel.
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! With such additional elements it is easy to emphasize the style of 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 the system unusual design. And in just 5 steps!
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
Among the disadvantages, we note that plastic, due to the peculiarities of its structure, can easily bend and deform during periods of temperature fluctuations. And in particularly hot weather, the plastic gutters even sag a little between the hooks if the fasteners were placed incorrectly and too far apart from each other.
Although, according to modern manufacturers, these disadvantages are insignificant compared to the advantages of plastic gutters. But when the time will come When purchasing 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 matched to the section plastic pipe and according to certain parameters, such as installation method, planned load and aesthetic aspect. Therefore, we have our own brackets for gutters with square, trapezoidal, round and pipe holders 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 each 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 here: fasteners should not interfere with the free movement of the gutter due to temperature expansion.
Step 4. Cutting in the funnels and attaching 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 into funnel special elements“spiders” that 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 horizontal elements. Pay attention to the fact that if you hear a creaking sound from already installed gutters- that 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, just lubricate all the fasteners; in 80% of cases, this is all you need. 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 elbows. If eaves overhang you have a width of more than 25 centimeters, then place between your knees drainpipe. 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 the opposite direction and pressed 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 cut pipes that will not have a connecting raster.
To make it easier for you to understand the process, we have prepared detailed information for you. step-by-step master classes:
To form 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:
