  • More Info

    Designed for both residential and commercial dwellings, the Water Heater Auto-Shutoff Valve uses an automatic full-port, 1.25-inch motorized ball valve 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 1.25" valves. A water heater shutoff valve is also available for 1/2", 3/4" and 1" valves, each sold separately.

    Want the same protection on your dishwasher, toilet or refrigerator ice machine? Then check out the Floodstop 3/8 Compression Auto-Shutoff (sold separately). A washing machine shutoff kit and a icemaker/water filter valve shutoff kit are also available and sold separately.

    1 1/4 Floodstop FS125NPT. What a shame, nice brass and Stainless Steel valve. Our water pressue comming from the street is 100 pounds. This motor is NOT strong enough to open this valve under pressure. On top of that the gears that drive the ball vlave from the motor are cheap Plastic once a 10 cent 1/2 round gear breaks, the valve is junk! Its only as good as it weakest link and that would be a 10 cent piece of plastic!!

    It was easy to install - and worked fine when I tested it. However the connector between the sensor and its cable needs some attention to be sure it is connected firmly. The ability to use a push-button to turn the water on or off manually is handy! The plastic case on the battery compartment is a bit flimsy - but that shouldn't hamper operation. Once attached to the wall - it doesn't get touched
