Abstract
PURPOSE: To prevent pumps from chattering in such a way that a pressure detector for single pump drive commands in a pressure tank so as to close the using water volume immediately before stop of the pumps when the pressure in the pressure tank comes up to more than a certain value after start of pumps.
CONSTITUTION: A pressure detector 13 for single pump drive commands is provided in a pressure tank 5 in order to close the using water volume immediately before stop of pumps when it is more than Q5'. Thus, when the using water volume immediately before stop of the pumps is larger than Q5', pressure in the pressure tank 5 after stop of the pumps goes down lower than follower pump starting pressure, whereas since the follower pump does not start, the pumps can be prevented from chattering.
