Laying of water supply. Description

The laying of water supply and sewage 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, the laying of a water pipe in a private house begins with an entrance crane. 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 branches. As a rule, two highways are enough for a one-story structure.

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

It is recommended to connect the mixers to different lines. In 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.

The laying of the water pipe requires the use of special tools and devices. In particular, you need cranes, fittings, mud filter, fasteners, thermal insulation for pipes, check valve. Laying 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 the water pipe today is carried out using metal-plastic pipes. To create connections, a special soldering iron for metal-plastic is used.

Before you buy material, you need to make 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 up. To the result obtained, add about another three meters of the pipe, in reserve. As a rule, the sixteenth metal-plastic pipe is used.

Laying a water pipe involves the use of fittings. 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, whose diameter is fifteen millimeters, are used.

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