What should I pay attention to when testing water with radiator? What is the main cause of radiator leakage?

Radiator is a kind of heating equipment that many people choose at present, and it is also a relatively new type of heating equipment. As we all know, heating installation is also a hidden project, so after installation, it is necessary to carry out water detection like our water pipes to avoid water leakage. So what do you need to pay attention to when the radiator is pressed to test the water? What are the main reasons for the radiator leakage?

Non-household heating users: generally in non-household heating residential buildings, residents on the top floor should close the exhaust valve on the top floor before heating test; After testing the water, the top floor residents should cooperate with the heating unit and use the top floor exhaust valve to exhaust the air in the heating pipeline of the whole building.

Users of household heating: After seeing the notice of water test posted by the heating unit, all the air release valves of the heating in the home should be closed to avoid water seepage. After the heating is filled with water, residents should check the exhaust situation at home, that is, open the air valve to let the air out of the heating pipe, and then see if the closing and opening functions of the valve are in good condition. During the heating period, residents who go to other places for business or are away from home for a long time must inform the heating department or the residential property, and do not suppress the water test.

Main causes of radiator leakage:

In addition to the unqualified quality of the radiator, there are several possibilities for radiator leakage: First, the radiator has been used for a long time, and internal corrosion leads to radiator leakage, which leads to radiator leakage;

Second, the joint between the radiator and the valve is not sealed enough, or the pipe quality is unqualified and leaks;

Third, the radiator leaks due to the principle of thermal expansion and cold contraction. After hot water is injected, some radiators with poor quality burst and leak under pressure;

Fourth, after stopping heating every year, the water in the radiator will be drained, some cracks sealed by sediment will be exposed, and leakage will occur when refilling water;

Reason 5: When heating suppresses water testing, residents forget to close the air valve when opening it, or connect the heating device privately and change it, resulting in water leakage.

This is the end of the knowledge about radiator suppression. It is also very clear above, that is, what should be paid attention to when pressing and what causes water leakage. You can refer to it I would like to remind everyone here that if you encounter any problems, you should first find a radiator manufacturer or installation company to solve them, and never solve them yourself.
