Abstract
PURPOSE: To deliver fresh drink water at all times by opening a pressure switch to interrupt conduction of the power supply circuit for a controller when a specified pressure can not be attained in a tank thereby preventing a drain valve to be opened. CONSTITUTION: On condition that a drain valve 15 or a manual faucet 8 is closed, a pressure switch 24 for detecting the inner pressure of a tank 3 decides whether city water supply is suspended or not by checking the water pressure in a tank against a specified level. When a power supply is connected, a controller 22 functions depending on the fact that the pressure switch 24 provided for the tank 3 is opened or closed. When the pressure is 0 or negative due to suspension of water supply, for example, the pressure switch 24 is opened and the controller 22 is not conducted. When the inside of the tank 3 is pressurized, the pressure switch 24 is opened and electric current is not applied to the controller 22. Consequently, a timer functions to open the drain valve 15 for a predetermined time thus replacing the water in the tank 3 entirely. Finally, the drain valve 15 is closed to prepare for normal water injection.
