Is household water tank cleaning a mandatory part of property services?

The government department in charge of the property company is the "Real Estate Bureau". If you want to know the "property service level standard", you have to inquire about the city you want to know, and the real estate bureau will formulate the corresponding "property service level standard" according to the local situation.

Generally speaking, the property must regularly inspect the living pool, and regularly clean the living pool according to strict requirements to ensure its water quality reaches the standard. It seems that some cities have not mentioned it in detail (usually at least twice a year).
