How to replace a heating riser yourself and not flood your neighbors? Step-by-step instructions

Such an important element of the heating system as a riser is a pipeline that unites the elements of the premises heating network. This ensures a normal level of water circulation in pipes and radiators.

There are currently feeders And reverse risers. The first of them, the coolant is distributed through the radiators, while second remove the heat-released liquid further along the system. In case of use single pipe pipeline systems performs the two functions described above.

Features of operation

The service life of a heating riser directly depends on what material is it made of it is made. Currently, widespread the following types of these products:

1. Steel risers. Such pipes differ high level of durability, relative cheapness and a significant degree of reliability. In order to install such products, it is necessary to use special equipment, as well as have certain skills for installation.

   

2. Copper risers. Such products have extended service life. But at the same time, their cost is much higher than steel pipelines. Copper risers are not subject to corrosion.

3. Metal-plastic risers. The connection of elements of such devices is carried out using special fittings.

   This significantly simplifies the assembly process. Even people without the relevant experience can perform the installation. But it is very important to use professional equipment.

4. Polypropylene risers. These pipelines are popular because they allow achieving a monolithic structure at the joints. This is due to the fact that the joints are welded with a special soldering iron.
5. Risers from cross-linked polyethylene. They are quite easy to install in apartments. They are resistant to corrosion.

Currently, polyethylene, polypropylene and metal-plastic risers are the most popular. This is due to the fact that these products have an optimal price-quality ratio.

Exists some placement features risers in the rooms that you should pay attention to before starting work:

• installation must be carried out near external walls;

• If the room is corner, the main pipe should go through near the corner;
• Do not carry out welding work near flammable materials;
• the riser of a one-pipe system should not be closer than 15 cm to the window;
• the optimal length of the eyeliner is 40 centimeters.

If you follow all the above rules for installing a riser, you can equip the heating system as correctly as possible.

Replacement

In order to replace heating risers, it is important to carry out work in a certain sequence.

How to turn off the heating riser?

To begin with It is important to shut off the system. Most often in an apartment building this is done in the basement. This work should be carried out with the help of a plumber from the housing office. In case of an accident, calling a worker is free. In other situations, you will have to pay a state fee.

It is important to carry out all work as quickly as possibleThis is due to the fact that after the riser is disconnected, there will be no heat in all the apartments where the pipeline runs.

As soon as the riser is closed with a special valve in the basement, it is necessary drain from the pipeline all that is in it water.

How to remove old equipment?

After removing the entire volume of coolant, you can begin to remove the old riser. To do this, in the apartment cut off the pipes that go to the radiatorsThe choice of location is influenced by several factors:

1. Possibility of carrying out works from the next room. Experts recommend changing the pipeline through overlap. It is in these areas that corrosion deposits most often accumulate.
2. Convenience carrying out the work. In this case, you need to choose places where it will be easiest to carry out welding and thread cutting.

To remove the old riser, you need to use with a grinder. No other additional tools are required.

Thread cutting on pipes

First of all you need a file remove the chamfer. This is how the entry for the die is made. The holder with it is put on a part of the pipeline long sideThis allows the die to enter perpendicular to the axis.

Once all the tools are in place, it is time to cut the threads - no more than 5 threadsWhen the die reaches the edge, it should be pressed very hard.

Assembly

In order to assemble a new heating riser, you need to perform the following steps:

1. First, you need to remove the pipe with the threads that are already on it. pass through the ceilings. After this, it is connected to the riser using couplings. It is important to use for winding linen and paint or sealant and silicone.
2. After connecting it is worth it screw the tees onto the threadsThe distance from one thread to the second should be within 50 centimeters. This will allow you to avoid installing the eyeliner tightly in the future.
3. Next we need to Screw valves into tees. Long nipples in the form of pipes should be installed in them, onto which a lock nut is mounted together with a radiator cap.
4. Further it is established jumper in the same way as the coupling. This means that the long thread with the lock nut must be screwed into the tee. The short thread is wound up, after which it must be screwed into the valve. At the same time, the long thread is unscrewed from the tee.
5. Then it is wound up and clamped. lock-nut.

Remains connect radiator to the new riser.

Launch

Before starting the riser, it is necessary to to experience the whole system. This work needs to be done with an assistant, which will check for leaks. The process is as follows:

1. Having opened the valve on the jumper, it is worth turn off the taps, going to the radiators.
2. Necessary screw in the plugs or close the collection in the basement.
3. Costs open slightly valve on the new riser.
4. As soon as the sound of water ceases to exist audible, we can conclude that the system is filled. After this, all taps can be opened.
5. All that remains is to check all the connections presence of leaks.

At the end, it is imperative to bleed the air from the system by opening Mayevsky crane on the jumper near the radiator.

Replacing the riser is possible on your own

Replacing heating risers is fairly simple job, which can be done at home with your own hands. It is very important to do it correctly complete all stages installation of new equipment in accordance with the recommendations of professionals. To avoid the most common difficulties and problems, it is necessary don't forget to bleed the air from the system.
