| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a boost water supply system capable of detecting a drop in the charged pressure of a pressure tank connected to a distributing pipe that connects a water supply apparatus for low stories to a water supply apparatus for high stories. SOLUTION: The boost water supply system includes a first water supply apparatus BP1 for low stories connected to a main water pipe; a second water supply apparatus BP2 for high stories connected in series to the first water supply apparatus BP1 and disposed in a position higher than the first water supply apparatus BP1; and the pressure tank 30 connected to the distributing pipe that connects the first water supply apparatus BP1 to the second water supply apparatus BP2. The first water supply apparatus BP1 and the second water supply apparatus BP2 have pumps respectively, and the second water supply apparatus BP2 issues an alarm indicating that the charged pressure of the pressure tank 30 is not in a normal range when the suction side pressure of the second water supply apparatus BP2 drops to a predetermined pressure drop detection value when starting the pump of the second water supply apparatus BP2.
