    The Flo by Moen Smart Water Shutoff is the industry-leading leak detection and water monitoring device for your home. Installed on the main water supply line, one device protects the entire home from supply-side water damage and leaks, guaranteed.

    The Smart Water Shutoff continuously monitors your home's water pressure, flow rate, and temperature. Using our MicroLeak™ technology, the Shutoff also runs daily Health Tests to identify any small leaks behind your walls, down to a drip per minute.

    Additionally, place your Smart Water Detectors anywhere in your home that may be particularly vulnerable to drainage or weather-related leaks. If an issue is detected, not only will you receive real-time notifications from your Flo by Moen App, but when used in conjunction with the Smart Water Shutoff, your Detectors can trigger the shut-off feature to protect the home from water damage immediately.

    The included Leak Sensing Cables add extended sensitivity to your Detectors, allowing for moisture detection across the entire length of the cable. Place around the base of a water heater, line a leaky window, or place along the base of garage and basement walls to keep your home secure.

    The entire system is supported by our FloSense™ AI, which learns the unique water footprint of your home to better identify water usage irregularities and inconsistencies, keeping you safer, faster.

Once installed you can prevent damage directly from the Flo by Moen App, anywhere in the world. Not able to get to your phone? Our system is smart enough to automatically shut the water off and protect your home.

A burst pipe can happen anytime, but with a Flo by Moen, you’ll catch it. Since the device is not dependent on Wi-Fi to turn off your water, you’ll be protected whatever the conditions.

The Smart Water Shutoff detects leaks as small as a drop per minute anywhere in your water system. This prevents problems like mold and helps you maintain a leak-free home. A Flo by Moen Health Test is automatically run once every day and you can also run them manually as much as you would like.

Manage alerts, see how much water you’re using, even remotely shut off the water manually, all from the app.

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!

Smartphone Control

The Flo by Moen App allows you to control your home’s water at your fingertips. With the Flo by Moen Smart Water Shutoff, remotely turn on/off your home’s water, gain insight on your water usage patterns, set water conservation goals, and more. With both the Smart Shutoff and the Smart Detector, receive alerts in real-time when an issue is detected.

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.
