Water Heater Shutoff, 3/4 Inch Valve
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.
