Installed a Flo by Moen on a 1" copper main last week; at 3:12 a.m. it pushed an alert for sustained 0.7 gpm with no fixtures on, auto-closed, and we traced a pinhole misting behind a dishwasher toe-kick in a 4th-floor condo before the subfloor got soaked. Reset was easy, but the homeowner’s had two nuisance trips during water softener regen — any tips on tuning the learning mode or adding sensors to cut false shuts without losing protection?
Nice catch — I had a Clack softener regen make our Flo auto-close twice; bumping the Continuous Flow shutoff time to match the regen (about 90 min) and setting sensitivity to Relaxed, then running a manual regen during learning, stopped the false trips. It’s training the guard dog to ignore the mailman, and it’s been quiet since.
I cut my false trips way down by running the softener through a full cycle while using Flo’s “Fixture Learn,” so it could fingerprint that flow. Then I extended the Continuous Flow shutoff a hair past the typical cycle length and made sure the valve firmware was current in the app — teaching it the midnight salt bath is a friend, not a thief. If it still hiccups, Moen’s tips here helped me dial it in: https://support.moen.com/Flo.
