The first valve is installed on a first pipe line(110) to discharge bilge in an emergency of the ship. The pump is connected with the first pipe line and a seawater supply line(132). The second valve is connected from the pump to supply seawater to an engine room or firefighting equipment. The bilge waste line and the third valves are branched from a second pipe line(140) and connected to the sea to discharge bilge. The valve connective pipe connects the first and second valves so that the pressure of the pump in operation is transmitted through the second valve to the first valve and the first valve is closed.;COPYRIGHT KIPO 2010
