To facilitate a hose connecting work and lead out a water sucking hose in an optional direction by installing a back panel for covering a water feed solenoid valve, forming an opening hole for hose connection on the back panel, and providing a bathwater sucking hose to be connected to a water suction port.
When a bathwater course start button is pressed, a current is carried to a feed solenoid valve 31 for a prescribed time, for example, 15 seconds to supply tap water. The water leaving a discharge port is collided to the wall of a priming feed port 33, and part of the water is supplied as priming from the priming port of a casing cover 41 into a pump through a priming hose 34. After the lapse of 15 seconds, the current carrying to the feed solenoid valve 31 is stopped, the motor 43 of a bathwater suction pump is rotated, and the pressure of a suction chamber 41d is laid in a negative pressure by the rotation of a runner 42 to suck bathwater through a sucking hose 27 connected to a suction port 26a. An opening hole for hose connection is formed on a back panel for covering the water feed solenoid valve 31, whereby the connection of the sucking hose is facilitated.
