Abstract: A water closet is disclosed having a bowl with rim wash outlets and a tank connected thereto containing flushing water at a level where most of the water will not flow by gravity through the bowl rim outlets. A tank water withdrawing device is mounted in the tank and is automatically activated when flushing is initiated to withdraw water from the tank and direct it to the bowl rim outlet to supplement the volume of water flowing from a water supply inlet connected to the tank to conserve water usage and provide proper rim wash at low water supply pressure.
