Common Questions

The Shutoff Extension Kit includes a Shutoff Battery Backup and a 3-Pack of Smart Water Detectors. Every Detector comes with an optional mounting bracket and an optional Remote Sensing Disc. You'll also receive two Leak Sensing Cables.
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.
To install, simply plug the Smart Water Shutoff power cord into the Shutoff Battery Backup and plug the Shutoff Battery Backup into the wall. This also adds an additional 6-feet of power cord lenght. No pairing or additional setup is needed!
