Is a Smart Water Shutoff Valve Worth It? The Math

The Insurance Information Institute reports 1.5 water damage and freezing claims per 100 insured homes per year from 2019 to 2023, about 1 in 67 homes, with an average claim of $15,400.

A LexisNexis study of 2,306 homes with a Flo by Moen shutoff found 96% fewer water claims and 72% lower claim severity in the year after installation compared with similar homes nearby. Moen worked with LexisNexis on the study.

The Moen Flo and Phyn Plus are cut into the main water line, so a plumber is recommended. Clamp-on valve robots that turn an existing ball valve are a no-cut alternative.

Some will. Stand Insurance offers premium discounts for an active Moen Flo, and Liberty Mutual runs a Moen savings and install program, but no insurer publishes a set percentage. Ask yours before you buy.

About $222 a year in avoided water damage on average. Expected damage is 1.5 claims per 100 homes x $15,400 = about $231 per home per year, and the LexisNexis study found 96% fewer claims with a Flo, so 96% of $231 is about $222. What you personally save is mostly the deductible and the effect on future premiums, and the case is stronger with a finished basement, frequent travel or a second home.

Yes, if someone is usually home to act on the alarm. The Govee 3-pack gives three sensors with 105 dB alarms plus a Wi-Fi gateway for app, SMS and email alerts, but it cannot stop the water. Put them at the water heater, washing machine, under sinks and in the sump pit, where leaks often start.

Standard homeowners policies generally cover sudden and accidental water damage, such as a burst pipe, but not damage from a slow leak left unrepaired or from flooding. Flood coverage is a separate policy, through the National Flood Insurance Program or a private insurer. Check your policy wording and your deductible.

Match it to your main water line. The Moen Flo comes in 3/4 in (900-001) and 1 in (900-006) versions, and the Phyn Plus (2nd gen) handles mains up to 1-1/4 in with adapters sold separately. Measure the pipe near your main shutoff before you buy.

It limits the damage but does not stop pipes from freezing. If a frozen pipe bursts, the leak triggers the shutoff and stops the water, and the Moen Flo also monitors water temperature. To prevent the freeze itself, insulate pipes in unheated spaces and keep the heat on, no lower than 55 F per the American Red Cross.

Closing the main valve before a trip is free and stops a burst hose or pipe from running for days. An automatic shutoff such as the Moen Flo does the same thing when nobody remembers, and it also catches leaks while you are home.
