A valve assembly is disclosed which is adapted to fit existing valve bodies. A flexible diaphragm assembly positioned within the valve body seals against a cylindrical barrel of the valve body. A central tube positioned within the central barrel defines a bypass passage extending from an upper chamber above the flexible diaphragm assembly and communicating with a bypass orifice. A sealing mechanism operated by an automatic control mechanism is adapted to selectively seal the bypass orifice. The automatic control mechanism includes a proximity sensor.
