Abstract:
1. A flusher for use with a water storage tank, comprising: an intake valve connected to an external water source and constructed to close water flow to a water storage tank at about a predefined water level in said water tank; a diaphragm-operated flush valve constructed to control a flush valve member between a seated state and an unseated state allowing water discharge from said water tank into a toilet bowl; a diaphragm, separating a flush-valve chamber and a pilot chamber, arranged to seal said flush-valve chamber and thereby maintain pressure forcing said flush valve member to said seated state preventing said water discharge from said water storage tank to said toilet bowl; a pressure control mechanism constructed and arranged, upon actuation, to reduce pressure in said pilot chamber of said diaphragm-operated flush valve to cause deformation of said diaphragm and thereby reduce pressure in said flush-valve chamber causing said water discharge; and a sensor module located at a reference location external to said water storage tank being at an input line coupling said external water source to said water storage tank.
