Abstract (en)
[origin: WO9717500A1] A system for detecting and locating leaks in vertical water supply pipes in a building. The system consists of a leak water retaining device (4) combined with two separate electrodes (6, 7). The water establishes contact between the two electrodes connected to a central unit that actuates a solenoid valve. The leak water recovered in a container (1) is discharged into the waste water down-pipe (10). If the down-pipe is blocked, the device uses the resulting backflow to trigger the closure of the collective solenoid valve. Said system is particularly suitable for preventing water damage resulting from a riser leak or congestion in a waste water down-pipe.
