Guardian GLD1 Leak Prevention System By Elexa

Save yourself thousands of dollars in water damage by using the Guardian Leak Detector. Whether you're worried about a broken washing machine, an overflowing sump pump, or a leaking water heater, Guardian has your back! Install the Guardian Valve Controller (sold separately) over your existing metal quarter turn ball valve (from 1/2 - 1) in minutes without any tools or pipe cutting, and place the Guardian Leak Detector near any appliance or fixture that might leak. The moment the Leak Detector senses water, extreme cold, or an earthquake, they will automatically shut off your water main to prevent further damage, and you will receive a notification on your phone via the Guardian app.
