Roof Tank Fill Pump

A roof tank fill pump moves water into a tank located on or above the building roof. The water then returns to the building and is pressurized by gravity as it falls.

In a roof tank system, the city’s water main enters the building and is connected to a roof tank fill pump in the basement. The fill pump sends water up through a supply riser to one or more roof tanks. A float gauge in the roof tank signals that the water has dropped below a certain level and the tank needs to be replenished. Since the roof tank fill pump is a gravity-based system, water travels down to the main pipes, called overheads, and supplies water to each floor, where they branch off to feed the fixtures.
