ABSTRACT:
A faucet control device to provide asepsis and conservation of water consisting of a diaphragm valve block connected inline between the hot and cold water supply and faucet. Pilot hot and cold water pressure from said valve block is routed through three flexible conduit assemblies to a three-way valve remotely located to facilitate operation by knee, foot or elbow. The application of force to the three way valves cycles the diaphragm valve block from the closed to open position while preventing crossflow between the hot and cold water supplies.
