Flo by Moen 900-001 – 3/4" Smart Water Shutoff with Leak Detection

Engineered for whole-home water protection, the Flo by Moen Smart Water Shutoff (Model 900-001) is a 3/4" inline monitoring device that combines real-time leak detection with automatic water shutoff. Designed for installation on the main water supply line, it allows contractors to deliver clients a comprehensive solution for preventing costly water damage while gaining valuable system insights.

Advanced Monitoring. Immediate Response.

Once installed, the system actively monitors pressure, flow rate, and temperature within the water line. When irregular activity is detected—whether a pinhole leak or a burst pipe—Flo by Moen can automatically shut off water to prevent damage. Users can control and track system status remotely via Wi-Fi through the Moen Smart Water app.
