Installation of drainage system: materials, general rules

It is impossible to overestimate the need to remove thawed and storm water from the entire structure and from the roof surface. Today, manufacturers offer for sale a wide range of products that can perform the role of such a system. Such designs are durable, easy to install, attractive in appearance and have a wide color spectrum. If you have some skills in construction, installing a drainage system will not cause any special difficulties. In addition, each manufacturer today provides instructions on how to conduct work, which helps organize the drain on its own.

Component systems and materials used

Any drainage system has the appearance of a system that provides for the presence of pipes and gutters, the diameter depends on the sewage load per running meter of the roof surface. The gutters are fixed to the construction with the help of hooks and brackets, gutters and pipes are connected using funnels. Fix the pipes to the house with clamps. The building can have different architectural features, depending on which the system can have as follows:

• Plugs and connectors of gutters;
• Pipe tips;
• Corner elements of the trough;
• Pipe bends.

Angle components of the gutter are designed to bypass the building at the inner and outer corners. But the pipe bends are required for making folds. The tips for the pipes give the completeness of the entire structure. If you will be installing gutters, then you can choose a rectangular or circular cross-section of the elements. The width of the trough will depend on the area of the roof and varies from 100 to 200 mm. The diameter of the pipes can be equal to 75-120 mm. As a rule, metal or plastic is used for fabricating a drainage system. Galvanized steel is almost not used for the reason that it is susceptible to corrosion processes. Titanium and copper can act as materials for the drainage system, but in this case the elements will cost more. Before installing the drainage system, it is important to take into account the materials and color of the roofing, as well as the external walls of the building, the architectural concept of the building, the amount of annual precipitation, the roof configuration and its total area.

Location of drains

Installation of gutters should be made taking into account the length of the roof overhang. If the overhang has a length of up to 10 m, then 1 drain is required, whereas if this is larger, two runoff should be prepared. The installation and location of these elements will depend on the type of roof.

Preparation of tools

To carry out works on the installation of a water drain, a certain set of tools should be prepared, among them:

• rope;
• Rivet pliers;
• Rubber and metal hammers;
• Scissors for metal;
• Drill with battery or screwdriver;
• pencil;
• Hydraulic level;
• Tool for bending hooks.

General rules for installing a drainage system

Where to begin? Installation of the drainage system should begin with the installation of hooks. They can be long, adjustable or short, and fastened to the lower board of the lath, from above the rafters or to the rafters. For each such technique, different types of hooks should be prepared. The next step is to calculate the angle of their inclination. The recommended slope should be approximately three meters per meter. Hooks should be placed side by side, numbered, and after marking the fold line. Next, a tool is used to bend the hooks, with the help of which the elements need to be bent over the markings. The installation of the first hook is carried out in such a way that the step between the extension of the roof and the outside of the chute is approximately 25 mm. The installation of hooks should be carried out at a distance of 0.9 m, while the angle of inclination should be equal to the limit of 2 to 3 mm relative to the horizon. The installation should begin at the edge of the eaves, from which the slope will go in relation to the horizon. The last and first hooks should be located from the edge of the roof edge to 150 mm. If their installation is carried out not on the front plate, but on rafters, then you should make grooves. This will allow you to compare the surface of the hooks with crate or rafters.

Methods of work

Installation of the drainage system in the next stage provides for marking if holes in the funnel are to be made in the gutter. When cutting the material, you can use a hacksaw. The funnel should get the necessary shape with the help of ticks, and the burr should be disposed of. The location of the material cut is treated with paint to prevent corrosion. When pruning metal is not recommended to use a grinding machine. The funnel is fixed to the outer bend of the chute, the clamps are clamped from the inside. The next step is to install the gutter stopper with a rubber hammer, but this method is sometimes replaced by hand-pressing technology. The design must be hooked by the way each hook is pressed.

Recommendations for joining gutters

When installing the drainage system with your own hands, it is important to correctly connect the gutters. This can be done with the help of connecting locks. Between the ends it is necessary to leave a gap of 3 mm, and on the rubber gasket it is necessary to apply the sealant in three lines, one of them should be located in the center, while the others - on the sides. The back of the lock should be fixed to the inner sides of the gutters. The lock should be pressed to the outside, which will ensure a tight fit of the gasket. Then it should be snapped and secured with clamp terminals. Remains of the sealant must be disposed of.

Possible mistakes

The rules for installing a drainage system say that if you increase the distance between the brackets, this can cause slack in the gutters. Among other things, you may encounter overflow if the roof edges do not coincide with the central part of the chute. Too much clearance between the trough line and the extreme part of the roof can cause overflow and splashing.

Features of the installation of plastic gutter

Drains for plastic roofs are installed by a certain technology, it provides for the first stage installation of funnels, which are divided into water intake, storm and roofing. The next step will be the installation of hooks, and then strengthen the holders, which are installed 2 cm from the funnel. To check the slope it is necessary with the help of a kapron thread, and with respect to the funnel the angle of inclination should be 2 °. When installing roof gutters plastic, where the length of the wall varies from 10 to 20 m, then the chute can have a simple or double slope. In the first case, the funnel should be located at the end of the ramp, while in the second it goes to the middle or from the middle.

A simple slope provides for the location of the middle trough at the highest point, whereas with a double slope at the highest point, two extreme troughs should be located, with water moving to the funnel in the middle. If the gutter length is more than 22 m, then it will take three funnels or a more powerful system. In the next step, it is necessary to install a trough connector, which can be compensatory or conventional. Gutter connectors should be located between the brackets, and the distance between them must be equal. At the next stage, the master cuts the trough into individual blanks of the required length, and protects the cutting places. Then you need to connect the funnels of the gutter, the last of which is placed on the brackets.

Conclusion

How to install the hooks of the drainage system, was described in detail above, but if you do not plan to do this work yourself, you can see the prices for the services of professionals. For the installation of the water drain experts will take 350 rubles. For the running meter, as for the installation of peaks and troughs, the cost will be equal to 230 rubles. For running meter. Prices for installing a drainage system are not too high, therefore, homeowners often resort to professional help.
