The water supply and sanitation system, which was originally laid during the construction of the house, sooner or later, is unusable. Pipes begin to flow, risers clog, after which their throughput is reduced. Therefore, prudent owners do not wait until the system fails, and carry out its repairs in advance. So, how can the pipes be replaced in the apartment and whether it is possible to independently perform these work?
Replacing water supply pipes
The overhaul of the water supply system begins with the dismantling of old pipes. The served equipment is trimmed through a grinder. If there is no way to dismantle the pipe to the riser, you will have to purchase a special adapter that will allow you to combine the cast -iron part of the water conduit with the new branch of the system. After time, the cast iron becomes very fragile, so the pipes should be replaced very carefully so that their fragments do not clog the riser. It is also recommended to put on a respirator, and protect your eyes with special glasses.
When choosing the material of the future water flow, you should focus, first of all, on your financial capabilities. The most popular today are considered pipe from propylene. The main advantages are the strength, durability and flexibility of this material. They also have a disadvantage — a fairly high price. Therefore, if there is a capital replacement of water supply pipes in the apartment, then you need to calculate that the repair will cost a lot.
A more economical option — metal -plastic. This material is quite affordable and easy to install. Pipe connection is carried out by means of fittings, and for cutting the structure you will have to use special scissors or a hacksaw for metal. Widely use ordinary plastic pipes today. They are less reliable, but have a low cost. For their installation, a special soldering station will be required.
Installation of water meters
Installation of the water supply system includes such an important stage as the installation of water meters. As in the case of the replacement of pipes, this operation can also be carried out completely on its own. And for the result to be successful, it is important to consider the following points:
You need to choose the right place of installation of a water meter in the apartment. Place the device so that you can easily remove the readings of the water meter. It is necessary to take into account the possibility of dismantling, since it often happens that the filter of rough cleaning is clogged, and you have to remove the water meter and clean it.
Before installing apartment water meters, you need to make sure that the input feed crane is working. Experts advise just in case to replace it. Before replacing the crane, it is necessary to block the water supply.
If the apartment has a hot water supply, then their counter is acquired under each pipe. Water meter for cold water cannot be used on a hot pipe.
The water meter is installed horizontally. There are models of meters that work in an upright position, then they should have a mark of BH AV.
If the water car has two or more risers, then the counter will have to be put on each.
Before connecting the water meter, you need to contact the utilities of the water supply with a statement on the installation of a water meter.
At the output of the counter, a check valve is mandatory, which prevents the change of direction of rotation of the device. If this construction element is not installed, the utility service may refuse to seal the water meter.
The required direction of water movement can be determined by special signs on the lid of the device.
Repair of a water supply system is always a troublesome and complex business, requiring certain skills and knowledge. Therefore, if funds allow, it is better to seek help from professionals.
