Wireless Foot-operated Stop Valve
A water-control system has a faucet, a base unit having at least one normally-open solenoid-operated valve coupled to a water inlet fitting and a water outlet fitting, control circuitry, and a first antenna, and an elongated foot switch, having a normally-open contact element, a battery, and circuitry including a second antenna. A water-supply conduit is coupled to the water-inlet fitting of the solenoid-operated valve, and a water line is connected between the water-outlet fitting of the solenoid-operated valve and a fitting at the adjustable faucet, and wherein, with the faucet open and water flowing from the faucet, stepping on the foot switch closes the normally-open contact element, causing a signal to be sent wirelessly from the elongated foot switch to the solenoid control circuitry, causing the solenoid-operated valve to close, stopping water flow from the faucet, and releasing the foot switch allows water flow to resume.
