Don't risk your floors, carpets and other personal belongings to costly and ruinous water damage! Prevent flood damage and avoid costly repairs with the easy-to-install Washing Machine Valve Shutoff Kit. This system not only detects leaks early, but it automatically shuts your water off in the event of a leak, alerting you with the control panel's alarm. Designed for both residential and commercial dwellings, the Washing Machine Valve Shutoff Kit uses a pair of automatic 9VDC 3/4-inch full port motorized ball valves to shut off the water supply whenever your washing machine leaks. The non-intrusive devices can be installed in as little as 10 minutes; no professional plumbers are required. This kit includes everything you need to protect your property from costly water-leak damage: valves installed on your hot and cold water inlets, a water sensor to be placed on the floor, and the control unit, which is mounted to your wall with the included screws. A power supply is included; you can also install four C batteries (sold separately) for backup power if desired. You can even add multiple water sensors for different areas around your washing machine. If your washing machine should begin to leak, the controller tells the water valves to close and alerts you with an 87db alarm. The system can also connect to an alarm, an automatic phone dialer, or both. Want the same protection on your dishwasher, toilet or refrigerator ice machine?
