Replacement of pipes in the apartment: the replacement of water pipes and heating in the apartment house

Apartment buildings are equipped with centralized water supply and heating system. The system presupposes the existence of distribution structures, for water and heat must be evenly distributed throughout the premises.

Communications centrally served in the basement of an apartment building, and from there on the distribution network is distributed from door to door. Inside the dwelling allocation is made on the inner tube. Each of them has a certain life span, eventually it comes into disrepair and required replacement of damaged pipes in the apartment. Sometimes the tenant himself is willing to change the outdated system of cast iron to plastic version. They are more modern and practical in use.

For whose account is under renovation

When it comes to replacement of pipes and water heating in an apartment house, consider some nuances:

• If the house is assigned the repair of utilities, he held management company home forces;
• Repair a failed sewer riser also be carried out at the expense of the management company, as it is obschedomovoy property;
• On communal responsibility lie repairs in the apartment of the state of employment, but if the owner is a private person, all the costs will fall on his shoulders.

So do not hurry to invest money in repairs where we need to do it more.

Types of pipes for heating and water

If it was not in the Soviet times much choice and almost all apartments were metal and cast iron risers, today a variety of materials for the manufacture of pipes has to only wonder. If necessary, replace the water pipes and heating in the apartment do not blindly go on about the applicant, it is necessary to understand which types of materials exist at present.

The choice of material for water supply and heating system

This process must be approached responsibly. After all of this in the end will depend on the extent to properly exercise their tasks the system utilities. If the buyer is an amateur, he is difficult to understand the wide variety. The choice of material from which the pipe is determined by specific operating conditions and technical buyer budget. When it comes to the sewage system, the selection priority will be Plastic pipe. Much more difficult to choose them for water.

Replacing the water pipes in her apartment implies precise knowledge of what the system is designed to supply clean drinking water and which for its disposal. In such water is contained in a large amount of oxygen and a small amount of salts. Pressure in designs with pure water is not more than 5 bar, and the temperature is within 60 degrees.

For repairs choose the following types of materials:

• Production of copper. Like it or not, and on either side of such a pipe is best suited for water. Copper, being a natural material, for thousands of years has been used for storage and transportation of water. With respect to copper exhibits water inertness. Exhibits this metal and bacteriostatic properties. It inhibits the growth of microbial flora. On the smooth wall of the copper pipe is not deposited salt. Anyway, in this respect, they are much better than steel pipes. For compounds of the present plumbing capillary brazing material is used, that the quality is similar to crimping.

The service life of a copper pipe larger as compared with a plastic one. Sometimes they are longer than the building itself. The only significant drawback of limiting their widespread use is the high cost. But when you consider all the costs of operation and maintenance of other systems, this option has a certain appeal. If the length of the copper water supply is small, low cost fittings which makes the design of the installation profitable;

• Pipe made of plastic and Metallpolimers. This option is suitable to owners of housing with a small budget. The cheapest is a polypropylene water. But when it comes to hot water supply, it is necessary to use plastic pipes with reinforcement. Connect such tubes via diffusion welding. Carry out installation work can not any person, but only the one who is qualified. Suffice slightly superheated pipe and is melted;

• Articles of polyethylene repoussage. Their reliability and price occupies an intermediate position. Crosslinked polyethylene and metal and plastic are similar in appearance, but differences do exist. Polyethylene have greater resilience, but the plasticity is more pronounced in reinforced plastic. Repair of communication with these pipes is much easier;
• Steel products durable, but can corrode because oxygen dissolved in water is a strong oxidant. Besides, the walls of this design become rough due to the fact that the deposited salts. But oddly enough, they are best suited for the replacement of old pipes in the Khrushchev. The point is that just because the material made all communications in older homes, and for the repair requires the same type of product.

Feedback from professionals is the best copper pipe. If your budget is small, you can use plastic and metal pipe. But the metal, it is strongly not recommended, especially in older homes.

Fittings - a separate type of water supply systems, with which the system is mounted plastic. With them, a compound of the one-piece nature. SNIP lets you embed them in the building structure. In the most extreme cases, use a threaded fitting, since the compound should have accessibility for maintenance.

Replacement and repair of heating materials and stages of work

Elements of such systems operate in very severe conditions of high temperature and pressure. Again the best in this case is a copper pipe. In addition, they have several positive qualities:

• Durable, plastic and resistant to mechanical stress. Because have a presentable appearance, they can be mounted an open manner;
• Exhibit low resistance. They can be used with a smaller outer diameter, resulting in significant savings;
• The material is not capable of burning, and in the case of fire, they will not release toxic substances;
• Copper pipe is not deformed at a maximum pressure;
• Resistant to corrosion. This distinguishes it from other metal products;
• Pipes are connected by soldering, which is safe for the interior of the room.

As already mentioned, the lack of copper pipes is their high cost.

Metal and plastic products for the heating installation

For repair and heating installation can be used galvanized metal pipe. They are reliable, resistant to corrosion due to deposition of zinc and capable of withstanding high temperatures.

Cheap plastic pipe for heating can be used if the coolant has a temperature of not higher than 75 degrees. They regularly serve the owner of just a few years.

Phased implementation technique works

Before you carry out installation of a new heating system, or a dilution water with their hands, should be carried out work on dismantling the old cast iron pipes. Performing such work has some features as it is a very fragile material. This is especially true of those communications that were exploited in the house very long. At work it is necessary to take care of personal protective equipment, the kit which must include glasses.

If we use a metal hammer when hitting the iron may crack or fly off piece of material. For the person conducting the work of dismantling, it is unsafe. Therefore it is better to use such a hammer, which has a rubber or wooden butt. Ideally, the pipe must be removed down to the riser. If this fails, you can use the plastic adapter.

Used for cutting cast iron grinder. In its absence, you can use an ordinary hacksaw. But at the same time, we must understand the process will be more time-consuming and costly effort.

Substitution heating pipes

It does not interfere with pre-read, what type are heating systems. They can exist in two forms:

• one pipe. hot water supply is carried out through the riser vertically. Such risers are performed diameter of 25 or 32 mm. For the wiring tubes are 20 mm in diameter;
• A system of two elements. One is used for hot water supply and the other for its retraction. When the device of such systems diameter determined by the number of radiators, which are expected to be installed. If the battery is 8, the use of the pipe diameter of 32 mm. If the radiator is smaller, the products are 20 mm. As also used riser pipe diameter of 32 mm.

Work should be done in the following order:

1. First, you must drain all the water in the system.
2. Fastener scheduled point location. Thus use perforator which operate holes.
3. If the one-pipe system, the top of the radiator must be installed crane Majewski. With it will be removed air trapped in the system. The hole at the bottom of tightly stoppered.

1. cranes then installed. To do this, use the special key with cap nuts. When the radiator is hung already be, conducted thereto assembly suitable conduit.
2. If the two-pipe heating system, is carried out in a semi Stroebe (deepening). They fit into the pipe, wrapped in insulation. In a similar way in the wall hidden structure that goes to heating radiators.

Newly Made system is checked for leaks by means of hydraulic tests. This is carried out at elevated pressure, which is 1.5 times the normal value. In this regard, one can give advice to a current two-pipe heating system water should be carried out in reverse. In this case, the air rises upwards and remove it by Majewski crane.

Water supply system

Most often one can observe cases of replacement of cast-iron water pipes with plastic or metal and plastic versions.

Replacing communications Khrushchev fraught with some difficulties. This is the old panel houses, where it is necessary to dismantle the structure very carefully, otherwise you can damage not only the system of hot and cold water, but do overlap. It is dangerous for the integrity of the house.

Given this, the installation carried out as follows:

• First necessary to block the water is supplied to the riser;
• The system disconnects all sanitary equipment;
• It is necessary to dismantle the old pipes. They should be cut and remove from the ceilings;
• Using a cutter, the pre-cut design elements to the desired length. When this verification is carried out with the developed circuit water. When cutting should not forget about the account of the fitting depth. If, say, the pipe length of 40 cm, it is necessary to cut 43 cm. 1.5 cm is added to the planting depth of the fitting;
• If you plan to connect a polypropylene tube on its own, then put on a special soldering iron tip. After that the product should be heated to the required temperature. Its value is specified in the instructions. Usually, it is 250 degrees. The connection is made carefully to avoid leaks during operation of the system. The pipe must be kept on the nozzle for 5-10 seconds. Thereafter, the joints were combined and await complete cooling;

• Replacement begins with the sewer pipe in the apartment. Then you need to solder taps;
• After the wiring is carried out towards the different rooms (bathroom, toilet, kitchen).

Work does not involve particularly complex, and with some dexterity it can be done quite independently. This requires the exact observance of milestones and accuracy.
