Abstract: Systems and methods are provided for automatically actuating preexisting water shut-off valves. A coupling of a valve actuator is connected to a handle of the valve, such that a motor of the valve actuator causes the selective opening and closing of the water shut-off valve. A controller monitors and controls valve actuation by controlling the motor. In addition to actuating the water shut-off valve upon detection of leak conditions, the controller may actuate the valve in order to test the water supply system or to test operation of the water shut-off valve. The operating status of the water shut-off valve may thus be monitored in order to detect or address problems with the water shut-off valve to prevent unexpected valve failure after a leak is detected.
