Save yourself thousands of dollars in water damage by using the Guardian Leak Prevention System. 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 over your existing metal quarter turn ball valve (from -1) in minutes without any tools or pipe cutting and place the Guardian Leak Detector near any fixture that might leak. The moment the Leak Detector senses water, extreme cold or an earthquake, it will automatically shut off your water main to prevent further damage and you will receive a notification on your phone via the Guardian app. The Valve Controller has an optional battery backup and works without the internet, so it will protect your home even without electricity or internet. The wireless Leak Detector can be placed up to a 1000 ft. away from the Valve Controller, to cover even the largest homes and their batteries last for up to 15-years. Over a 100 additional Leak Detectors can be added to protect properties of any size. The Valve Controller will test your valve every week to make sure it is working properly during an emergency and will alert you if anything goes wrong. The system includes a Valve Controller, a Leak Detector and 1 Remote Sensor that plug into Leak Detectors to extend it to hard to reach areas. Use the free iOS and Android app to configure your system and monitor or control it from anywhere, with no monthly fees or other equipment.
