Abstract
A fill valve for a water storage tank, the fill valve comprising a riser assembly, a valve housing mounted on an upper end of the riser assembly, a pilot orifice in the valve housing, and a sensor adapted to be mounted within the water storage tank. The sensor is responsive to a water level within the water storage tank, and a pilot valve mechanism opens and closes the pilot orifice in response to the sensor determining the water level in the fill tank.
