Why chatter heating pipes

Living in multi-storey buildings, many tenants hear extraneous clicks, humming in the heating system. This is due to violations of the rules of operation and installation.

Heating pipes are made of steel, which conducts sound waves well. The round shape of the pipes also does not prevent this.

Noises of heating pipes vary. It may be:

• rumble;
• crackling;
• periodic clicks;
• knock.

All noises reduce the comfort of living, and often cause leaks and accidents. Why do the heating pipes knock, you will learn by reading this article to the end.

How to deal with the buzz in the pipes

Hum in the pipes of heating occurs for several reasons:

1. During operation, the diameter of the pipe decreases.
2. Water leak.
3. Installation of pipes of smaller diameter.

If the heating pipes are humming, the first thing to do is look for a water leak. Most likely, it is located in the basement. It is easy to detect by a cloud of steam and a stream of water.

You call a plumber who fixes a leak. The hum in the pipes should stop.

Reducing the diameter of the heating pipe is another reason for the hum in the pipes. You can detect the place of noise by ear. Walk along the pipes and try to find the cause of the noise. As a rule, the source of the hum is in the basement, where the pressure in the pipes is greater than in the apartments.

The narrowing of the diameter of the heating pipes may occur for the following reasons:

1. Faulty and improperly installed valves that do not guarantee protection of the system against ingress of rust, slag or foreign particles into it.
2. Formation of plaque inside the pipes, which reduces the diameter of the pipes, as a result, pressure increases in them.

The hum is eliminated by replacing old pipes and valves with ball valves, they almost do not have such problems. You can open the water discharge valve located above the intended point of constriction. Foreign particles, if they are in the pipe, will be released from the heating system.

The water in the batteries rages and clicks

Such noises occur in the air-conditioned heating system, and they can also be caused by debris that has entered the system after it has been repaired.

The air from the system is removed by means of a Mayevsky crane, through which air is discharged from the heating system.

If, after this, the noise has not stopped, then a possible reason is improper installation of pipes connected to the heating radiator. A slight bias may be the cause of unpleasant sounds.

Cracks and clicks can be caused by the presence of debris particles in the radiators, by the break of the ventilation valve. Open the tap and drain the water; particles may come out of the heating pipes.

Knocking on the pipes

A broken vent valve can cause a knock on the heating system. This happens when improper installation. If the valve is installed in the opposite direction, then the erosion will result in its breakage, as a result, there will be a knock on the heating pipe.

Open vent is a serious accident. A sharp increase in water pressure can lead to gusts of pipes in the heating system. Riser urgently need to block and call the plumber. After the repair, the knock should stop.

Extraneous noise may occur due to water temperature fluctuations. Everyone knows that when heated, metal objects expand and contract as they cool. If the brackets that fasten the pipes are installed poorly, they can cause knocking. When the temperature fluctuates, they will move and knock on steel heating pipes.

If you live in the house of an old building, then this is the main cause of knocking. It is necessary to go through and check the mounting brackets, if necessary, to carry out repair work.

Service providers claim that the temperature of radiators and pipes is constant, but this is not entirely true. It often happens that hot water flows through the heating pipes and then cooled down. An open window in the apartment may cause a brief knock on the pipes.

At the entrances of your houses, you often see open windows, broken windows, and all this leads to temperature fluctuations in the heating system, which means that knocking occurs in it.

If the brackets are loose, but pressed to the wall, there will be no knocking, an unpleasant creaking sound will appear.

After examining the causes of noise in the heating system, you can make a unifying conclusion - the reason in the old pipes and radiators. Eliminate them all and immediately can only be making a quality overhaul of the entire heating system at home or entrance. But it can wait for a very long time and not wait. Therefore, in the summer period, apartment owners should do an inspection of the heating system and eliminate minor problems.
