PROBLEM TO BE SOLVED: To provide a pressure feeding device capable of ensuring an acceptable amount for receiving drainage before the drainage comes into the pressure feeding device from respective water-discharging equipments. SOLUTION: The pressure feeding device provided and connected with the downstream side of a water-discharging equipment has a shape of outer profile for storing water inside while including a pressure feeding pump inside. The device also is provided with a drain control means for detecting inflow of the drainage. Thus, the drain control means detects inflow of the drainage, so as to drive the pressure feeding pump before the drainage flows into the pressure feeding device from the water-discharging equipment. Accordingly, the drainage within the pressure feeding device starts to discharge the water before the drainage from the water-discharging equipment flows into, so as to ensure an acceptable amount for next drainage.
