Stop A Flood in Its Tracks

When you pair the water and freezer sensor with our smart water valve, your system detects leaks, sends alerts, and automatically shuts off the water supply — minimizing costly damage. 




Safeguard Vulnerable Areas

Guardian Protection-powered sensors monitor for leaks in hard-to-reach places: under sinks, behind washers, beside sump pumps, or under water tanks. With the optional sensing cable, detection can extend along floors or behind appliances where water might accumulate unnoticed.
