| Zusammenfassung: | A water leakage detection system includes: a solenoid valve that is provided to a water pipe having at least one feed-water valve on a downstream portion of the water pipe, and is configured to be set to at least one stage of a partially-opened state between a fully-closed state and a fully-opened state; a flow meter that is disposed on a downstream side of the solenoid valve; and a controller that controls an opening/closing state of the solenoid valve, and receives information on a flow rate detected by the flow meter. The controller detects water leakage in the water pipe when the solenoid valve is turned to the fully-closed state, and thereafter when the solenoid valve is set to the partially-opened state at a time point when a predetermined time elapses, and thereafter when the flow meter detects a flow rate. |
