Save yourself thousands of dollars in water damage by using Guardian Leak Detectors throughout your home. Whether you’re worried about a broken washing machine, an overflowing sump pump, or a leaking water heater, Guardian has your back! The moment a Leak Detector senses water or extreme cold, they will automatically send signal the Valve Controller (sold separately) up to 1,000 feet away (line-of-sight) to shut off your water main to prevent further damage. You will receive system notifications on your phone via the Guardian app.

The average U.S. home is estimated to need 6 to 8 Leak Detectors to properly cover the most common areas where leaks occur: toilets, refrigerators, freezers, water heaters, washing machines, dish washers, HVAC, basement doors, sump pumps, sinks, drains, etc. Our three-pack is a convenient option to help configure your sensor setup.
