Why do we live in a tall building? Turn on the tap 24 hours a day, there is always water! Is there a pump that keeps pumping water?

I read a news recently, that is, the problem of secondary water supply for high-rise buildings. Generally, households living above the seventh floor eat secondary water supply. Consulting residential property can be known for a long time.

The secondary water supply system is generally an enlarged sealed reservoir on the roof to solve the water problem of high-rise residents. Whether the reservoir is sealed and cleaned regularly can be jointly supervised with the user.
