Abstract
A domestic water valve assembly protects against water leaks by closing a valve if a leak is detected. A leak is detected when a water flow rate falls below a predetermined low flow rate for a length of time longer than a predetermined time-out period or when the water flow rate exceeds a predetermined high flow rate. The predetermined high flow rate, low flow rate, and time-out period may be changed by an operator. When a leak is detected, a control system activates an electric motor to close a valve, the valve remaining closed until reset by the operator.
