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.

Steer Clear of a Winter Washout

A frozen pipe is a flood waiting to happen. The sensor’s built-in freeze detection alerts you when temperatures drop toward freezing, helping you take action before ice forms. Combined with your system’s smart water valve and temperature sensors, you can react fast to protect your plumbing during extreme cold.
