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 float arm of a combination float and float arm has a first end pivotally connected to the valve housing for opening and closing a pilot orifice in the diaphragm valve. 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. A snap off cover member extends over, and is releasable latched to, the valve housing and the float housing.
