Abstract
A fill valve particularly suited for OEM assembly in gravity operated flush toilets has a modular construction including a main valve body that encloses a pilot operated diaphragm valve operated by a float arm. A hollow riser has a lower end configured for connection to a water supply line. Mating couplers are provided on the bottom of the main valve body and on the upper end of the riser for rigidly securing the riser to the main valve body. The riser has a length that is pre-selected to place the diaphragm valve and float arm a predetermined height within the tank to ensure that the tank is re-filled to a predetermined optimum level.
