摘要

The device (1) has different supply lines (7) assigned to flushing pipes (9), which communicate with a waste water outlet (12), where the outlet is attached to a public waste water network. A motor-operated house connection check valve (6) closes a house connection (3) against the supply lines. A water sensing device (17) is installed for detecting a leakage in a room of a building (2) e.g. hospital. A control device (15) is arranged in such a manner that the house connection check valve is closed in the case of leakage detected by the water sensing device and/or a pressure sensor (10).
