Does the maintenance of residential gas regulator belong to property management?

Gas is generally not within the scope of property management. You can contact the gas company. If you really can't contact the after-sales, you can find a master to repair it yourself, such as Ian Lianbao. Of course, if your gas is under warranty, the after-sales maintenance of the gas company is the best choice. Regular maintenance must be carried out without paying attention to the safety of use. I wish you a happy life.
