<p>A fill valve for a water storage tank includes a riser assembly, a valve housing mounted on an upper end of the riser assembly, and a pilot operated diaphragm valve mounted in the valve housing. A float housing is connected to the valve housing. A combination float and float arm has a first end pivotally connected to a valve housing cap for opening and closing a pilot orifice in the valve housing cap. A second end of the float arm is connected to the float. The float is located in the float housing which has an inlet opening for allowing water to spill into the float housing so that the float rises upwardly and the first end of the float arm fully seals off the pilot orifice. The first end of the float arm has a central arm and a pair of flexible pivot arms that are laterally displaceable for engaging a pair of spaced apart fixed pivot pins on the valve housing cap.</p> |
