Installation and replacement of water supply. Special tools

Replacing the water main (house or apartment - is not important) is an actual problem for many residents. First of all, this procedure is carried out at the end of the service life of steel water and sewage pipes. They can be destroyed due to corrosion, metal decay or non-observance of the operating pressure in the system. Replacement of the water supply in the apartment requires special skills. Therefore, it is better to hire specialists who will do the job quickly and efficiently.

Special tools for the replacement of a water pipe

Lerca is a tool that serves to create threads on a water pipe or other similar products. Replacement of the water pipe is not without this device. It is a metal nut in the hole which contains special teeth.

General information about the lighter

The teeth are placed at different angles so that during the rotation of the nut on the water pipe, a thread is created. Edges are cut with the help of a cutting element - a cone. Their number may be different. As a rule, the creation of threads on the water pipe is carried out with the help of a single round lumber. Such a device is mounted on a special surface and can have up to five cutting elements. Special tools of the tongue when replacing the aqueduct of a round kind allow to cut metric and inch threads. The tool has a significant advantage. The work involves all three edges, so the thread is created in one pass.

One-piece and sliding laker

When replacing pipes of water supply or sewage, it becomes necessary to create a thread. The most popular devices are integral and sliding lasers. The first type allows you to get quality turns on the pipe in a short period of time, while getting not only a metric but also an inch thread. The process passes quickly, because the tool is made of quality hard metal.

Its disadvantage is a short service life. Such devices are used in the case when it is not necessary to observe exact parameters when creating coils. During operation, the tool can spring, which leads to a change in the diameter of the water pipe. This difference is insignificant and is only 0.1 mm. Another negative feature of the integral linter is a low degree of rigidity, because of which the thread does not always turn out clean and correct.

The sliding-type device has in its complete set special guiding elements, thanks to which the creation of thread is easier. Such a tool consists of several parts that are attached with screws. The latter elements serve to regulate the accuracy of the turns. To make the thread creation process more efficient, you need to purchase a set of dies that serve to cut a variety of diameters. It does not need to spend much time and effort.

Operating Tips

The replacement of the water pipe is accompanied by the creation of threads on the pipes. To ensure that the final result was of a high quality, and the cutting device did not fail, it is necessary to adhere to certain recommendations:

• Thread creation is performed only by a working tool;
• Cutting elements must be sharpened;
• Before starting the water pipe must pass a number of preparatory stages: the surface is removed paint and dirt;
• At the end of the pipe, a chamfer is made with a file or a grinder;
• In the process of work, it is necessary to periodically lubricate the cutting elements. To do this, there is a tool that has a peculiar composition.

Completing of the work

With the help of a laser it is possible to quickly and accurately create the required type of thread, regardless of the type of water pipe. The work should be performed in the following order:

• The water pipe is fixed in a vice (you can use other tools).
• The pipe is cleaned of dirt and paint, then with the help of the file, the outer chamfer is removed.
• Inserted a fork with a pre-installed nozzle for the required diameter.
• Cutting elements and pipe are lubricated with a special tool.
• Lerca should be perpendicular to the axis of the pipe. If the device is installed at an angle, the thread will be of poor quality, and the diameter of the pipe will change.
• The clock is rotated clockwise. It should be smooth, without sharp jerks.
• After achieving the desired result, the lerca rotates in the opposite direction, thereby removing the metal shavings.
• During operation, it is necessary to periodically lubricate the pipe and cutting elements with a special substance.

With what to begin replacement of water and sewer risers?

If you live in a multi-storey building, the replacement of the water supply or sewage system begins with the receipt of a special permit. It can be obtained in the housing maintenance service. In addition, neighbors are warned about the forthcoming work. Switch off the water supply only by a specialist. Replacement of risers of water supply and sewage can be carried out by all the entrance. This procedure will be much easier and cheaper. Therefore, this issue is best coordinated with all tenants and find a common solution. If the solution is positive, the riser can be made of polypropylene. Otherwise, the owner of the apartment will have to re-assemble steel pipes or spend money on adapters from metal to plastic.

Material of risers

Choose the right material - not such a difficult job. Replacing the water pipe is preceded by the selection of main and auxiliary pipes. They are made of the following materials.

Steel

Such pipelines are capable of withstanding large pressure and temperature changes. The negative sides of this material include the occurrence of plaque inside the pipeline, the susceptibility of corrosion arising during operation. In addition, the installation is quite laborious, since it is necessary to use a welding machine. Pipes are used for the installation of water and sewage systems.

Polypropylene

Despite the light weight of the pipes of this material are quite strong and are able to withstand pressure and temperature changes. To install them requires the presence of butt elements, a soldering iron, a laser, etc. The mounting can be done independently. Among the shortcomings are the impossibility of analyzing the finished structure. If one of the elements breaks down, it is necessary to saw the entire structure. It is used not only for sewer and water risers, but also for other branches.

Replacing the water riser

Before the installation of the mechanism, the valves are replaced on the water pipe or the installation - in the absence of them. Old systems are equipped with a crane. To avoid leakage, it is better to cut it and install a ball valve. It is located closer to the riser on the return. The installation process begins with the inspection of the butt joints at the neighbors. If they have plastic pipes installed, the fastening will not cause any special difficulties. The polypropylene structure is connected by means of a soldering coupling. If neighbors have steel pipes, then you will have to make a special adapter from metal to plastic. Such places should often be checked for strength, as leaks may occur. You can do this yourself. However, if the steel tube is not satisfactory, it is better to call the master. If the installation of the adapter is incorrect, it will burst. With the help of a special device (thread) the thread of the corresponding diameter is cut. It is best to make 5 turns. Another way to connect metal and plastic is to install a collet with an internal thread. In order to keep it better, use a sealing material - a tape tape. The coupling is wound on a steel pipe, then a polypropylene pipe is connected with a soldering iron. After completing all the work, the entire system is checked.

Replacement of the water supply system

When installing the sewer pipe, it is necessary to dismantle the old structure. The steel pipe is cut with the help of a grinder so that there are indents above and below the structure. The top margin is 10 cm, and the bottom is about one meter. And this is the distance from the tee. Completely cut the pipe is not worth it, because in the future there may be problems with the installation. A wooden wedge is inserted into the cut off top and hammered. Beat with a hammer until the pipe bursts around the perimeter. Further, the wooden wedge is pulled out and a conical chamfer is made with the help of the Bulgarian. It is done on undisturbed elements. The lower part of the sewer riser is a piece of pipe and tee. These elements are pulled out manually, by rocking the pipe in different directions. In case of difficulty, the tee is cut off by the Bulgarian. This releases the bell. Then it must be cleaned of dirt and dust. The new riser is first assembled in the draft version, where the fixing point of the main and auxiliary elements is determined. The bell is placed in the plastic tee, and their diameters should have the same value. Otherwise, you will need to install an additional adapter. If the construction is assembled correctly, it is dismantled, and clamps are fixed to the wall, which will fix a new sewer riser.

Installation of sewerage system

For the beginning, the cuffs are installed faceted outward and lubricated with a special sealant. It is also necessary to handle all structural details of the future sewage system, for example, chamfers on pipes and adapters. The whole construction is assembled in the same sequence as in the draft version. All connections must be carefully assembled to prevent leaks. The last step is fixing the screws on the mounting clamps.

In some cases, a replacement or installation of the tee is required. Many experts recommend plunging the tee into the sewer pipe in the following sequence:

• The necessary place in the riser is carved with the help of a Bulgarian.
• All edges are treated with a file or other grinding device.
• The pipe, on which the compensator will be located, is lubricated with a sealant.
• The compensating element is mounted on the pipe. There must be room for mounting the tee.
• The pipe is lubricated with a sealant, and a special tee is attached to it.
• The small side of the compensating element is lubricated with a sealant and connected to the pipe in such a way that it fits snugly against the tee.
• The design is ready for use. Further assembly takes place in the same sequence.

Conclusion

Replacement of the water supply and sewerage system is a responsible activity, which specialists must deal with. The more quality work is done, the longer the system will last. You can do this work yourself, but you need to have some experience in this industry and a set of special tools. The replacement of the water supply in Samara is carried out by a team of specialists who will perform the work quickly and qualitatively. Finding appropriate specialists is usually not difficult.
