Mercury now requires smart water leak detection on some new HO-3 policies, moving the devices from discount to condition of coverage.
Starting May 29, 2026, Mercury requires qualifying smart water leak-detection devices on certain new standard HO-3 policies. Carrier partnerships with Phyn and Moen Flo are expanding, and Phyn cites a 99% reduction in non-weather water claims across a 13,500-home study.
Why it matters
Water mitigation is the volume engine of most shops. If carriers successfully push shutoff devices into a meaningful share of homes, the frequency of the burst-pipe and slow-leak jobs that pay your trucks goes down.
Our assessment
Read as a homeowner convenience story, this is a pleasant bit of technology news. Read as a market story, a carrier just started shrinking the water mitigation volume your trucks run on, and it is not sharing the savings. Add prevention to your offer before the losses thin out: sell, install and monitor shutoff devices for the property managers already on your call list.
