Help! ! The house smells of gas, all the time. I asked the property manager, but the property manager said he didn't know! Who should I ask for help?

First of all, confirm before the warranty, whether it is air leakage before the table or after the table. Close all valves. At this time, check the reading of the gas meter and record it with a pen. Later, check whether the reading of the gas meter has changed. If the reading does not change, it belongs to air leakage before the meter. You must ask the gas company for warranty and let them check it. It is possible that the leak is somewhere else. Turn off all valves, including gas stoves, and the main valve must also be turned off. If the reading changes, it belongs to air leakage behind the meter, and the air leakage point must be in your home. But it is more troublesome to find the air leakage point. Be patient, remove the valves and put them on the boring head, then check the meter reading and remove all the valves in turn until the meter reading remains the same. If all valves are generally inspected and no leakage points are found, it is that there is something wrong with the gas pipe joint. It is best to carry out the above inspection by yourself, or you can ask the property manager for help.
