LeakBreaker ® is a water heater leak protection device that protects against flood damage from the containment failure of a water heater. It consists of a control unit, a valve with actuator and a sensor. This re-settable, testable protection device can be installed on any style water heater to shut off the incoming water supply, preventing additional water flow to a damaged water heater. The two-color LED light and audible alarm lets you know the status of LeakBreaker ® at all times.
