Laying of water supply. Description

The laying of water supply and sewerage is an integral part of repair and construction work. For the correct and technically competent installation, a design diagram of engineering communications is drawn up.

As a rule, laying a water pipe in a private housestarts with the input tap. After the mud filter is installed, then the check valve, then the meter showing the water flow, the tee, then the two cranes on the highway. This will result in two water pipes. As a rule, two highways are sufficient for a single-story structure.

The laying of the water supply system includes the connection of the toilet bowl, the equipment for water heating, the mixers for the kitchen sink and the bathtub, the washing machine.

It is recommended to connect the mixers to differenthighways. In the case of repair of one branch, this will allow to continue to use water. Repair can also take a few hours, or even a whole day. Specialists recommend installing the valves on cold and hot water in front of each mixer. In this case, the repair will not affect the availability of water.

Прокладка водопровода предусматривает use of special tools and devices. In particular, you need cranes, fittings, mud filter, fasteners, thermal insulation for pipes, check valve. The laying of the water pipe is carried out using metal pipes with a diameter of twenty-five millimeters for passage in the wall openings. The length will depend on the thickness of the wall. To drill holes in the wall, you need a drill with a shock mechanism, a six-millimeter drill bit, a knife for cutting pipes from metal-plastic, a gas and wrench, a punch and a drill.

Laying of water pipes today is carried out using metal-plastic pipes. To create connections, a special soldering iron is used for metal-plastic.

Before you buy material, you need tomake certain calculations. To do this, you need to decide how exactly the roads will go. Then, using a tape measure, you should measure the distances between the walls where the pipes are supposed to pass. After measurement, all distances are added. To the result obtained, add about another three meters of the pipe, in reserve. As a rule, the sixteenth metal-plastic pipe is used.

Plumbing involves the use offittings. They are different. Calculate their exact number is complicated. This is due to the fact that in the process of working some of them may not be useful or something, on the contrary, will have to be bought.

Important parts of the water pipe are the cranes. As a rule, traditional bronze or ball valves with a diameter of fifteen millimeters are used.

Laying of water pipes is carried out with the use of thermal insulation material. It prevents condensation, which can create serious problems.

Fastening of pipes is carried out with the help of fixatives. These devices, in turn, are fixed with the help of "driven" - sets of steel screws and plastic dowels.
