Save yourself thousands of dollars in water damage by using the Guardian Leak Prevention System Plus. 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 ½” - 1.25”) in minutes without any tools or pipe cutting, and place the Guardian Leak Detectors near appliances and fixtures that might leak. The moment the Leak Detectors sense 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.
The Guardian System was built from the ground up to be completely bulletproof. The Valve Controller has an optional battery backup and works without the internet, so it will protect your home even without electricity or the internet service. The wireless Leak Detectors can be placed up to a thousand feet away from the Valve Controller, to cover even the largest homes, and their batteries last for up to fifteen years. Over a hundred additional Leak Detectors can be added to the system to protect properties of any size. The Valve Controller will even test your valve every week to make sure it is working properly during an emergency, and it will alert you if anything goes wrong. The Guardian Leak Prevention Kit includes one Valve Controller, three Leak Detectors, and two Remote Sensors that plug into Leak Detectors to extend its reach to hard to reach areas. Use the free iOS and Android app to configure your system and monitor or control it from anywhere in the world, with no monthly fees, dedicated hubs, or other equipment. For indoor use only. LET’S STOP WATER DAMAGE!
