Guardian can prevent water damage in three easy steps:

1. Install 2. Connect 3. Protect



No Tools Needed

The Valve Controller installs out of the box, with no tools – hand-tighten the clamps to secure everything to your valve.

Use Your Existing Valve*

You don't need a special valve or tools to use Guardian - just a standard quarter-turn ball valve.


Guardian will open and close your valve weekly to keep it in good condition and ensure proper operation during emergencies.


Battery Backup

Battery Backup

With the optional battery backup, Guardian will protect your home and shut off your water supply during leaks for up to twelve hours without electricity.

Offline Functionality

Offline Functionality

Once configured, the Valve Controller will still shut off your water during a leak, even if the internet is down. WiFi is only required for setup as well as off-site control and monitoring of the system.

Extreme Long Range

Extreme Long Range

The Water Detectors can be placed up to 1000' away from the Valve Controller, which means Guardian will protect large homes and even apartment buildings.
