Baotou Zhongguan Environmental Protection Technology Development Co., Ltd. - What Should Heating Companies and Users Pay Attention to After the Heating Season Ends?
QShould the main valves of the supply and return water pipes at home be closed after heating stops, and why?
AIt is recommended to close the main valves of the supply and return water pipes in a timely manner, which helps keep the radiators and pipes in a full water wet preservation state, reducing the risk of corrosion caused by air entry. It can also reduce the probability of leakage that cannot be handled in time due to no one being at home during water filling and pressure testing in the next heating season. Specific operations can be carried out according to the instructions of the heating unit in the community to ensure the valves are properly closed.
QDoes the water in radiators and pipes need to be drained after heating stops?
AGenerally, draining is not recommended. The water in the system is mostly softened water, and retaining the water can isolate air from entering the radiators and pipes, thereby delaying rust and extending service life. If renovation, disassembly or maintenance is required, professional personnel should be contacted to avoid leakage or damage caused by improper operation.
QWhat should I do if I find water seepage or leakage at radiator joints or valves after heating stops?
ASlight water seepage may occur due to thermal expansion and contraction after heating stops and temperature drops. You can first use a container to catch the water or use a towel to absorb it and continue to observe, as some situations will resolve on their own within a few days. If the leakage is large, continues to worsen, or affects walls and floors, you should contact professional maintenance personnel as soon as possible. Do not disassemble heating facilities by yourself to avoid greater leakage and property loss.
