Guardian by Elexa, Leak and Flood Prevention System GVD3

Save yourself thousands of dollars in water damage by using the Guardian Leak Prevention Kit. 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") 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 Water Damage Prevention 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. 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!

Ease of Use:


  • Worth it for less worrying!
    Verified BuyerReviewed by 27NoWorries - November 29, 2019

    I bought this for the shut off valve capabilities as I live in a 2nd floor apartment and the valve for my washing machine isn’t accessible in the closet, so it gives me peace of mind to know if there’s a leak, the main valve in the basement will shut off all water to the house. My only complaint is that the sensors are bigger than I expected and can’t be pushed under the machine. Of the 3 sensors that came with the system, only 2 have extensions with smaller sensors. It is unfortunate that the main sensors aren’t really usable unless you have an appliance that is higher off the floor.

  • Beats my old sensor
    Verified BuyerReviewed by Ralph - July 28, 2019

    I had a battery powered leak sensor in the tray under my water heater. It would sound an alarm if it sensed a leak. If I was not home that was just my bad luck. When the battery was low, it would start to beep, usually waking me in the middle of the night. This new sensor comes with an automatic shut off valve that shuts off my water main if it sense a leak and notifies my smart phone! While the shut off valve plugs in, the sensor is still battery operated but its a much longer life lithium battery. The unit comes with three sensors to place where ever there might be a leak. My only complaint is that the Android and Apple apps are a little glitchy during the setup process. However, once set up, they seem to work fine.
