Protect Against Fixture Leaks & Environmental Damage

Complete your Smart Water Security System with customizable Smart Water Detectors. Simply place the discreet 3.5” Detectors in an attic, basement, laundry room, or anywhere that is potentially vulnerable to water damage by environmental factors or fixture malfunctions. If you also have the Flo by Moen Smart Water Shutoff, a leak sensed by the Detector can trigger the shut-off feature to protect the home from water damage.

Reviews & Highlights

5.0/5.0

"Placed one of your Detectors under the window of an unused guest bedroom a few weeks ago. We forgot it was even there until it alerted us to a faulty window seal. With all the hurricanes passing through it could have been bad! I'm impressed."

- Mark J. Huntsville, AL

5.0/5.0

"Fantastic new addition by Moen! I've had the Shutoff installed for over a year and don't know how we traveled without it before. My wife and I have 6 Detectors throughout our home and pool shed. The peace of mind is A+. Can't wait to see what's next."

- Sam P. Cupertino, CA

5.0/5.0

"I had three major leaks that had to be repaired. Took cutting holes in the walls and ceilings to check. With this complete system, I now know whenever water is somewhere it shouldn't be and the Shutoff is there to cut the supply. AMAZING. Thank you."

- Felicidad F. Devon, PA

5.0/5.0

"This is the best new technology I have purchased. We travel and were constantly turning off our house water. This has really helped reduce my anxiety around water damage occurring while I’m away. I have been recommending it to everyone I know."

- Bob W. Northbrook, IL

5.0/5.0

"One of the best purchases we have ever made. Added the Shutoff and we've found small leaks that we didn't know we had. Also we travel a lot and can shut off the water from anywhere. We have recommended this system to everyone we know."

- Larry D. Bloomington, IL

Common Questions

Every Detector includes 1 CR123A battery, a Remote Sensing Disc for hard to reach places, and a hard case with adhesive back for easy mounting. Leak Sensing Cables are sold separately.
No. The Detectors will alert you through the Flo by Moen App with or without the Shutoff. But please note, without the Shutoff there will be no way for our system to automatically turn off your water and protect you from catastrophic water damage.
While the answer will depend on the temperature and humidity thresholds you set, most Detectors include 1 CR123A battery with a life expectancy of over two (2) years. You will also be notified via the Flo by Moen App if your battery is running low.
We recommend at least three (3) Detectors per home to accommodate the highest-risk areas like water heaters, refrigerators, and washing machines. More would be needed to cover sink drains, basement corners, or other areas prone to environmental damage.
