Abstract

PURPOSE: To deliver fresh drink water at all times by providing a water storage time detecting means and a suspension of water supply detecting means and opening the drainage valve in the drain pipe of a water storage tank automatically for a predetermined time when a water injection time can not be attained within a specified time. CONSTITUTION: A water injection sensor 23 measures the current-carrying time for water injection by providing an operating lever 9a with a solenoid switch. A pressure switch 24 detects water level in a tank lower than a specified level and determines suspension of city water supply. When 12 hours elapses after a set switch 25 is depressed to open a drain valve 15 and discharging water, a controller 22 decides whether the integrating time of the sensor 23 is longer than 4 min or not and makes a decision that the water of 12 hour before is left in the tank if the integrating time is shorter than 4 min. The drain valve 15 is opened after deciding that the inside of the tank is pressurized and the water in the tank 3 is replaced. When a water injection valve 9 is opened longer than 4 min, the drain valve 15 is opened forcibly to discard the water in the tank 3 it 24 hours has elapsed after depressing a set switch 25.
