About The Moen Flo Smart Water Monitor

Water damage is the most common home insurance claim — and most of it is preventable. The Moen Flo Smart Water Shutoff installs directly on your home’s main water line and uses internal sensors to monitor pressure, flow rate, and temperature around the clock.

If it detects anything unusual — from a pinhole drip to a burst pipe — it shuts the water off automatically and sends you an alert through the Moen Smart Water App. Unlike systems that use ultrasound to listen from the outside, the Flo monitors the water moving inside your plumbing, detecting leaks as small as a single drop per minute during its daily microleak test.

The app is free with no subscription required and works with Amazon Alexa, Ring, Alarm.com, and NICE. Insurance discounts may be available through participating providers.

How The Moen Flo Smart Water Monitor Works

FloSense™ Technology learns your home’s normal water patterns. Anything outside those patterns triggers an automatic response — not just an email.

24/7 water monitoring

Continuously tracks flow rate, pressure, and temperature in your home’s main supply line, day and night, whether you’re home or away.

Automatic shutoff

When a leak is confirmed, the device closes the valve and stops water flow immediately, before you’ve even seen it on your phone.

Real-time alerts

Receive notifications by app, phone call, or email the moment anything is detected. Control your water remotely from anywhere in the world.

Daily microleak test

Runs an automatic test every 24 hours to detect leaks as small as one drop per minute, long before they cause visible damage.

Water usage tracking

See your home’s usage history, flow rate, and pressure by fixture. Identify where you use the most water and spot billing anomalies.

Freeze alerts

Detects frozen pipes and sends an alert before they burst, a critical feature for Pennsylvania winters.

Sizing isn’t guesswork

The Flo comes in three configurations. An incorrect pipe size affects performance and may void the warranty. Haven confirms your main line size before anything is ordered.

Power & placement matters

The device requires a nearby AC outlet. Haven assesses your water main location and routes power correctly — no extension cord workarounds.
