Installation of pipes with your own hands: description, step by step instructions and recommendations

When the old water pipe rotates in the apartment,appear fistulas and sweat on the pipes, then there is a need to install a new one. You can do it yourself without obtaining permits and without making out papers. It is necessary to shut off the water supply in the risers, and then to do the work, after which you will be able to use the new system for more than a decade.

Procedure for replacing the pipeline

If you have started pipe installation, then you needguided by a certain technology, which at the first stage provides for the selection of material, as well as schemes for the distribution of cold and hot water. The next step will be the development of a water supply scheme, as well as the calculation of the diameter of the pipes for the material. The master prepares the mounting tool, acquires the material, and also dismantles the old pipeline and sanitary equipment.

For reference

After the new pipes are installed, it is possible to mount and connect plumbing. At the final stage, the boiler is installed and connected, if it is provided by the circuit.

Selection of material for pipes

Installation of pipes can be carried out afterpurchase of products. However, at the first stage it is necessary to select the material. Copper can act as a copper, but some experts do not advise using it, because, in contact with water, this material is able to form copper oxide.

Most often recently usedmetal plastic, such pipes are quite expensive, but you can connect them yourself without having a professional experience. Metal-plastic water pipes are connected to threaded units with fittings or gaskets. Such products can be bent, and the hydrodynamic resistance and pressure loss are very small. In order to introduce such a pipe into the fitting, you need a press pliers, a pipe cutter and a set of scans. Among other things, the life of the gaskets in the fittings is limited. It is required to know if you are going to hide the pipes.

Traditional solution

Installation of pipes can be carried out on the basis ofplastic products, which today are already generally accepted. You can use polybutylene with good bending ability, polyethylene, which is cheap but not able to withstand temperatures above 60 ° C, as well as polyvinyl chloride, which is well known for its chemical resistance, low cost and heat resistance up to 80 ° C.

Pipeline installation: layout drawing

Installation of pipes can be carried out on one of twoit can be parallel and consecutive. In the latter case, the points of analysis should be connected to the common pipe by means of tees. This scheme is considered the most economical, but with an impressive number of points of analysis or low pressure, it is unsuitable, since it greatly reduces the pressure. In this case, it is possible to use a parallel circuit in which the valves regulate pressure by points.

Peculiarities of installation of the pipeline system

If you decide to install pipes with your ownhands, then at the first stage it is necessary to install arcs, which are plastic strips for mixers. They should be fixed to the wall by means of dowels. When fixing, it is necessary to take into account the thickness of the finish, for example, tile or plaster.

The next step is to assemble the sections of the pipeline. The most accessible technology is the assembly on the table and the further installation of pipes. However, in this case, there may be a question about how to pipe through walls. If you use metal-plastic, there will be no special problems, since it is assembled with detachable fittings, whereas for brazed pipes one of the following methods can be used.

It is recommended to use adapters andmetal-plastic inserts. For an apartment this method will be sufficiently reliable, and in the corners above the pipes it is necessary to make removable hatches for repair of threaded joints and revision. However, it is possible to install the pipeline system in place, using a compact soldering iron for this. It costs more, and you need to work with it in cotton gloves, so as not to get a burn.

After it is possible to cut pipes, they can not be cut, thatespecially for metal-plastic. Cut it with a pipe cutter, for a metal-plastic and plastic such a tool has different characteristics. The next step will be soldering, one of them takes 15 mm of pipe. Between two fittings there can be one meter, for this it is necessary to cut off 1030 mm. If between them 0.6 m, then cut the workpiece into 630 mm. When the installation of water pipes, then the next stage they need to bend, the minimum permissible radius is 5 outer diameters. Do not use sand for this, which supposedly helps to bend the products to any angle. At the same time, the internal coating deteriorates, the residual voltage exceeds the permissible values.

After the water supply has beenThe boiler should be installed if it is present in your apartment. Pipes under it must be made in advance, but the valves are opened immediately after installing the pipe, in addition the nozzles are muffled.

Stacking of steel pipes

Installation of steel pipes, which are galvanizedcoating, can not be carried out by welding, but threaded connections are used quite often. This is due to the fact that under significant thermal loads, steel will burn out. The use of special modes of welding and filler materials will solve the problem only partially.

When installing steel pipes for water supply andHeating elements are connected by gas welding. This method allows you to achieve better connection of elements. In the pipe for this, a technological hole is cut, and part of the seam is superimposed from the inner surface. At the first stage, it is necessary to perform the marking and cutting of the material in those places where it is necessary to perform the docking. When grinding the edge, it is recommended to use an emery wheel. Next, the edges are prepared, this step is to give them a geometric shape that would facilitate an ideal fit.

If the thickness of the pipe is more than 3 mm, then for the arcThe weld bevel angle should be greater than 45 ° C. When gas welding, the edges should be melted by the flame at the place where the connection should be. In order to eliminate gaps, the molten metal should be applied between the pipe ends, filling the space with them. After the filler half is attached.

Piping of sewage pipes

Installation of sewage pipes providescompliance with a certain bias, which is necessary for the natural draining of impurities. If this parameter changes from 0.02 to 0.03 °, then the optimum speed of impurity movement will be approximately equal to 1 m / s. In other words, for each linear meter in a horizontally located pipe it is necessary to arrange a slope towards the drain 3 cm.

Installation of sewer pipes, whose diameter is notmore than 5 cm, should be laid with a slope of 30 mm per running meter. If pipes with a more impressive working diameter are used, the slope can be reduced to 20 mm per running meter.
