What to know
- Automatic protection: learns your home's usage patterns and closes the main line on its own when flow doesn't match.
- Daily microleak tests catch the tiny drips — a pinhole leak or a running toilet — before they become damage.
- Leak sensitivity down to a drop per minute, with app alerts and remote shutoff from anywhere.
- A professionally installed unit may qualify for homeowner's insurance discounts.
- Installed, calibrated, and documented by licensed Eco plumbers.
How Flo by Moen protects your home
The device installs in-line on your main water supply and monitors every drop that enters the house. Because it learns what normal looks like for your household, it recognizes what abnormal looks like — a burst washing machine hose at 2 AM, a failed water heater tank, a slow drip that never stops — and closes the valve automatically, then tells your phone what happened. You can also shut the water off yourself from the app, anywhere.
What it needs to work
Flo by Moen needs reliable 2.4GHz Wi-Fi and a nearby AC outlet, plus a compatible main line — most systems fit 3/4-in. to 2-in. pipe. It's best installed by a licensed plumber, and note that it doesn't offer standalone security-monitoring integration (if you want a monitored security tie-in, ask us about FloLogic instead) and the extended warranty is a paid add-on.
What professional installation covers
A smart shut-off only protects the home if it's set up for how that home actually uses water. Eco's licensed plumbers confirm main-line access and pipe compatibility, verify power and Wi-Fi at the install point, set up a bypass so water softener regeneration and irrigation cycles aren't flagged as leaks, calibrate the Home/Away flow sensitivity to your household, walk you through the app, and document the install — which is what many insurers require to apply a leak-protection discount.
Why leak protection matters in Puget Sound homes
Our region's older housing stock means aging supply lines and water heaters tucked into closets, attics, and crawlspaces where a slow leak can run unnoticed for weeks. An automatic shut-off turns a potential five-figure water-damage claim into a minor repair — and it's on duty when you're at work, asleep, or away.

Common questions
Will Flo by Moen shut my water off by mistake?
Not when it's installed and calibrated correctly. It learns your household's normal usage, softener and irrigation cycles get a bypass so they aren't flagged as leaks, and Home/Away sensitivity is tuned to your home during the install. If a false trigger ever happens, you reopen the valve from the app in seconds.
Does it qualify for an insurance discount?
It may — many carriers discount premiums for a professionally installed automatic shut-off because water damage is one of their most common claims. Insurers often require proof of professional installation, which is part of what Eco documents for you. Check with your agent for your policy's specifics.
Flo by Moen or FloLogic — which one is right for my home?
Flo by Moen is the home standard: app-based automatic protection with daily microleak tests. FloLogic is the monitored tier — the most sensitive detection (down to about a tablespoon per minute), battery backup through outages, and security-system integration, at a higher installed cost. We install both and will recommend the right fit during a free assessment.
Can I just rely on my manual shut-off valve?
A manual quarter-turn valve is reliable — when someone is home to close it. It can't detect a leak, alert you, or act while you're away, and that's exactly the gap an automatic system closes. If your main valve is old or seized, we can address that during the same visit.
