Guardian is a system of Leak Detectors and a Valve Controller that work together to detect leaks and shut off your water automatically, preventing further damage. Guardian installs with no tools, no plumber, and no pipe cutting – simply install, connect, and protect.

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 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.

  • Completely Standalone - The Leak Detectors communicate directly with the Valve Controller, avoiding the need for hubs or other useless hardware.
  • Extreme Long Range - Leak Detectors can be placed up to 1000' away from the Valve Controller, that's more that an entire city block.
  • Routine Self Tests - The Valve Controller will regularly check your valve to make sure it's not stuck during an emergency.
  • No Tools Required - Guardian installs without any tools or professional help – configuration usually takes under ten minutes.
  • Offline Functionality - Guardian will protect your home without internet connectivity. The internet is only required for initial setup, off-site control and notifications.


  • Install in minutes and never worry about water damage again. Guardian will automatically close your water main when Leak Detectors sense leaks, freezing temperatures, or earthquakes. Use the iOS & Android app, with no monthly service fees, to monitor and control your system from anywhere in the world.
  • Valve Controller easily installs over existing quarter-turn metal ball valve from ½” - 1” without any tools. For Indoor use only!
  • The Leak Detectors can be placed up to 1000’ away (line of sight) from the Valve Controller, and they include a 15-year battery.
  • The Leak Detectors sense water using five different points of detection to provide installation flexibility. Use to monitor toilets, basement doors, sump pumps, water heaters, appliances, sinks, drains, and more for leaks and floods.
