Abstract
A tank-type flusher is located in the water storage tank for flushing a toilet. The tank-type flusher includes an intake valve and a flush valve. The intake valve is connected to an external water source and constructed to close water flow to the water storage tank at about a predefined water level in the water tank. The flush valve is constructed to control a flush valve member between a seated state and an unseated state allowing water discharge from the water tank into a toilet bowl. The tank-type flusher may be controlled by a sensor module located at a reference location external to the water storage tank.
