Flo Automatic Water Leak Detector and Shutoff
Sits on the main line watching flow, pressure and temperature, runs a daily leak test, and shuts the water off itself.
What you're getting
- Monitors flow, pressure, and temperature on your main water line to catch unusual patterns.
- Runs an automated daily leak test so problems surface before damage spreads.
- Shuts off water automatically when a leak is detected, stopping a flood before it starts.
- Catches hidden leaks in walls and under floors that a human would never notice.
Why we picked it
This sits on your main water line and watches for the flow and pressure changes that signal a leak, then cuts the water automatically. Daily self-tests catch problems overnight.
