Smart water monitors for sprinkler leaks: Flume vs Moen Flo vs Phyn
A water monitor watches the whole property and alerts you to leaks, including a running sprinkler line. Flume straps on at the meter; Moen Flo and Phyn Plus go on the main water line and can shut the water off.
| Flume 2 | Moen Flo | Phyn Plus | |
|---|---|---|---|
| Where it goes | Straps on at the meter (Flume) | Main water line | Main line after the meter (Phyn) |
| Shuts water off | No | Yes (Moen) | Yes (Phyn) |
| Plumbing needed | No (Flume) | Yes | Yes; licensed plumber recommended (Phyn) |
Moen says an irrigation crack as small as a dime’s thickness can waste about 6,300 gallons a month (Moen). Need a plumber? ↓
How they differ
- Easiest install: Flume straps on with no pipe cutting and self-installs in about 10 minutes; Flume says it fits 95% of homes (Flume).
- Want automatic shutoff? Moen Flo detects leaks, alerts you in the app and can shut the water off (Moen). Phyn Plus can also turn the water off automatically (Phyn).
- Plan the install. Phyn installs on the main line right after the meter, needs Wi-Fi and an outlet within 12 ft, and recommends a licensed plumber because the line is cut (Phyn).
- Covering the sprinklers? Phyn monitors irrigation only if it’s installed before the irrigation line branches off (Phyn).
- Check your rebate first. Round Rock pays 50% up to $300 and names Flo by Moen, Flume 2 and Phyn Plus (Round Rock). Riverside offers up to $175 (RPU). IRWD offers $100 but does not permit meter-attached devices, so a meter-mounted monitor won’t qualify there (IRWD).
