How to open the valve when heating water injection is inhibited

Matters needing attention in hot water test:

When testing water, leave people at home, open the inlet and outlet water, and turn off the running wind.

Don't shake the radiator, and don't load the radiator and pipes.

At the beginning of water testing, open the exhaust valve to exhaust the air in the pipeline.

Once water leakage is found, the inlet and return valves should be closed immediately and the property department should be contacted.

If it is geothermal upstairs, pay attention to whether there are any signs of water leakage in the ceiling of the house.
