Moen Flo Smart Water Monitor and Automatic Shutoff

Moen’s Flo Smart Water Monitor and Automatic Shutoff is the latest entrant in the growing field of connected plumbing solutions designed to protect homes from water damage. The device combines real-time leak detection, remote monitoring, and an automatic shutoff valve that can cut off the main water supply when a leak is detected.

What sets Flo apart is its focus on actionable protection. When the system detects abnormal moisture patterns or sustained leaks, it can automatically close the water supply to prevent flooding. Homeowners can also monitor activity, review water usage, and receive push alerts via the companion app.

How it works

The Flo system sits inline with your home’s main water line and includes sensors that monitor flow and pressure. If a leak is detected or unusual usage occurs (such as a burst pipe), the system initiates a shutoff to minimize damage. The app provides a timeline of events and can distinguish between typical and abnormal water usage.
