This IntelliFlow automatic washing machine shutoff valve with leak sensor is used in residential applications to protect against catastrophic water damage from a burst inlet hose connected to a washing machine in use or unattended. It senses when the washing machine is on or off, and then opens or closes the hot and cold inlet valves as needed to allow or prevent water from flowing to the washer. If it detects a leak, current flow to both the hot and cold water valves are immediately interrupted and closed. This device consists of an electrical three-prong outlet to receive a washing machine power cable, leak sensor, power cord, and a replaceable internal strainer screen. It also comes equipped with 1/2 inch sweat inlet adapters for both hot and cold water supply tubing, a wall mounting box, and two mounting tabs used to secure the valve to the wall for surface mount applications. The maximum pressure is 150 psi.
