The Guardian Leak Prevention System comes with everything you need in an easy to install package. Installation only takes a few minutes and you never have to worry about water damage again. Guardian will automatically close your water main when the Leak Detectors sense a leak or a freezing temperature. Use the iOS & Android app, with no monthly service fees, to monitor and control your system from anywhere in the world. The system will automatically protect you from leaks even if your internet is down.
The Valve Controller easily installs over existing quarter-turn metal ball valve from ½” – 1.25” without any tools and features a splash resistant housing which means it can be installed outside in certain applications how ever indoor use is recommended.
There is no hub required as the valve its self is what joins the wifi network and allows you to use the mobile apps to manage the system. The sensors all communicate directly with the valve.


The Leak Detectors can work up to 1000 feet away (line of sight) from the valve and feature a 15 year average battery life.
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.
