How Does Moen Flo Work?

It connects to your WiFi, which allows you to monitor it from your smartphone (so if you are installing it in your mountain cabin, remember, you must have an internet connection). Because everything is controlled and monitored at the source, it doesn’t matter if it’s a toilet, shower, faucet, water heater, or pipe that is the problem, Flo has you covered. If the device observes any unusual behavior it will send alerts to your phone and if you delay in responding, it is smart enough to shut off the water supply automatically. Flo by Moen is able to accurately measure flow, pressure, and temperature with three sensors.
