The device has an inlet pipe (5) connectable to a domestic sewage line, and a drain line (6) connectable to a sewer. A pumping device (8) pumps sewage water (12) over pressure lines (10, 20) into the sewer. A shut-off device (7) i.e. pinch valve, stays in a directly or indirectly controlled connection with the pressure line and/or the drain line such that the shut-off device is shut when overpressure exists in the pressure line and/or the drain line. A membrane device (13) disconnects the flow of sewage water from hydraulic medium (14) to directly or indirectly control the shut-off device. The membrane device is a tensile hose. |
