"My 3-year-old left the upstairs spare bathroom sink on and I only discovered it after receiving a Flo by Moen alert that .40 GPM had been running for 23 mins. Imagine if that was running all day while I was at work? Thank you!"

- Leeann Z. New Jersey

"Shutoff was installed easy enough and appears to work as advertised. Still too early to give it 5-stars, though."

- Michael, Colorado

5.0/5.0

"Excellent product. I love the data it gives you to help reduce your consumption. Plus, I just sleep better knowing it is watching and protecting the house...cheaper than paying someone to visit the house when away. Plus, doesn't talk back. ; )"

- Mark Nevada

Common Questions

While the Smart Water Shutoff monitors your home plumbing for signs of compromise and dangerous leaks, it can't always detect fixture failure. Things like water heaters, sink drains, and refrigerators breakdown and leak outside of your core plumbing.
Nope! As of August 17th, 2020, we’ve discontinued the monthly subscription needed to unlock advanced data features. All features and data are now freely available to all Shutoff users.
No. You will also have full control over sensitivity levels for your home and when you should be alerted.
The Shutoff does require a normal 2.4 GHz Wi-Fi connection to setup and maintain consistent software updates. NOTE: The Smart Water Shutoff is Wi-Fi enabled, not dependent. Your water usage data is stored locally on the device in case of Wi-Fi outages.
