Before installing the drain with your own hands, it is necessary to dwell on the choice of the material of the system. The most economical are systems made of galvanized sheet metal. They are durable and easy to maintain, but they are rarely used in private construction at the moment. Popular systems are made of plastic, metal elements coated with polymers or painted metal. However, the most expensive option is a copper drain.
When installing the roof of metal roofs , a drainage system made of metal with a polymer coating is installed. Such material is unpretentious to changes in temperature. The only drawback is noise in rainy weather. The drainage system of PVC is installed on a roof made of the same material. Often, the internal drainage system is used, as a rule, in regions with a harsh climate.
The external drainage with their own hands must be mounted before the roofing works are done, since the holders of the system must be fixed to the front panel or to the rafter by means of pins with clamps. Then hooks and staples on which the gutters are placed are attached. When choosing a trench, it is necessary to take into account its variety and classification. To protect the gutter from damage by heavy rain or snow, fasteners are installed at a certain distance from each other. As a result, a slope should form between the first bracket and the last one. Then the cord is stretched between them for mounting intermediate fasteners. With the correct collection of gutters, the drainage system must function smoothly, while its edge is below the roof by 25 mm. We lay the troughs in the brackets, we work the joints with the sealant.
Create a drain with your own hands is not difficult. You will need a galvanized steel sheet 7 mm thick. First, a rebated joint is produced in the form of a bend along the length of the sheet. Then, with the help of the rolling tool, the iron is rolled before it is shaped like a cylinder - it will be a drainage pipe. Next, we begin to make a funnel, for which the rim, cone and glass are cut from the same material, but with the following rules: the diameter rim corresponds to the diameter of one of the sides of the cone with which it will fit, and the diameter of the main pipe should coincide with the diameter of the bottom of the glass , Otherwise leakage is possible. The funnel and pipe are joined by a seam seam. As for plums, there are no restrictions and rules. Often, in the manufacture of plums, the cut-off pipe, which is attached at an angle to the drain, is applied obliquely. When connecting pipes from two parts each next must be already previous by 5 mm, which improves the connection density.
Creating a drain with your own hands, you need to monitor compliance with the established rules. According to the norms, draining the water through the drainage system should be at a distance of 1.5 m from the building, in order to prevent moisture from getting under the foundation and foundation of the building. To do this, the drainage is extended by 2 m with a 10 cm diameter pipe . The pipe is filled with ground with a slope at the end below the level of the base of the house.
