Getting Started

The Smart Water Shutoff needs to be installed on the main water line of your home. For about a week, your device will be in “Learning Mode.” During this period, the Smart Water Shutoff learns the unique water usage patterns of your home.

  1. Pair your Shutoff with your Flo by Moen App
  2. Install your Smart Water Shutoff
  3. Wait 10 days for the Shutoff to learn your home
  4. Enjoy total protection

FloSense Intelligence

The Smart Water Shutoff has three sensors that actively monitor the flow rate, area temperature, and pressure of your home’s water 24/7. These sensors work in combination with our unique feedback-enhanced AI technology, Flosense ™, to proactively monitor your home for leaks of all sizes.

Your home is unique. So are your water usage habits. With this breakthrough in machine-learning, the more you interact with your alerts, the more intelligent your Smart Water Shutoff becomes.

Automatic Daily Health Tests

The Smart Water Shutoff runs automatic daily Health Tests with our patented MicroLeak™  technology to ensure that your home is leak-free. You can also manually run a Health Test at any time.

To perform the Health Test, the Shutoff will close its valve to prevent any water supply from entering your home so that it can monitor the stability of the water within your pipes. This daily test is automatically scheduled to run when you are least likely to use water. That’s how smart the Smart Water Shutoff is!

Customizable Security

Whatever your need, the Flo by Moen Smart Home Water Security System is designed to be customizable for all homes.

Real people, real Flo stories

We have an older home and my Pressure Reducer Valve (PRV) has **already failed once**...

Flo by Moen has exceeded even my fussy expectations!

Having now had my Smart Water Shutoff for several months, my only regret is that I did not get it sooner. I have never worried about damage from a fire or burglary, but I have been concerned about damage from a leak that might occur while we are away from home. We have an older home and my Pressure Reducer Valve (PRV) has already failed once, causing an increase in pressure that not only ruined my plumbing but also messed up my refrigerator and washing machine. Thanks to Flo by Moen, I no longer worry about a water leak or failure of my PRV, though. The Flo by Moen App is amazing, too. I love all being able to see the health of my home’s plumbing from anywhere.
