What problems should users pay attention to when the heating system suppresses water testing before heating every year?

Before testing the water every year, the heating unit will post a notice of heating and water supply in each residential building, or inform it by SMS or WeChat. The main content is to let users know the water supply time, contact number and contact person. In the meantime, users should pay attention to the contents of the notice and cooperate with the heating and water supply. In addition, check the indoor pipeline for abnormalities and lack of fittings in detail, and pay special attention to whether the manual exhaust valve on the radiator is missing to avoid running water.
