Don't risk subjecting your floors, carpets and other personal belongings to costly and ruinous water damage when it can be avoided before it begins. Prevent flood damage and avoid costly repairs with the easy-to-install Water Heater Auto-Shutoff Valve. 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. Incorporate the Flood Stop into your INSTEON or X10 network - the control unit has two output contact wires and plugs with 6" leads.

Designed for both residential and commercial dwellings, the Water Heater Auto-Shutoff Valve uses a 3/4-inch full port motorized ball valve powered by an AC/DC adaptor (or 4 AA batteries) to shut off the water supply whenever your water heater 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: a valve installed on your cold water inlet, a water sensor to be placed on the floor, and the control unit, which is mounted to your wall with the included screws. The Water Heater Auto-Shutoff Valve can be installed using two adjustable wrenches in minutes, although some older homes' valves might be soldered to the pipes, which would require professional installation.

If your water heater should begin to leak, the controller tells the water valves to close and alerts you with an 87db alarm.

This shutoff valve is made for 3/4" valves. A water heater shutoff valve is also available for 1/2", 1" and 1-1/4" valves, each sold separately.
