Introducing Flo by Moen: Smart Home Water Monitor & Leak Detector

moen flo smart water monitoring with smartphone appThe new Flo by Moen smart home water monitoring system and leak detector is an excellent solution for homeowners looking for peace of mind. This Moen Flo leak detection valve is great for tracking your water usage so you can change habits to save on utilities and lessen your environmental impact. Still, maybe the best benefit is that you can catch leaks before they become disasters. If you have a vacation home, a cabin, or rental properties, or just somebody who goes on extended vacations, this is a great way to stay on top of potential plumbing problems. There are 2 options, depending on pipe size:

How Does Moen Flo Work?

It’s straightforward, Flo by Moen is installed on the main water supply line to track all usage. 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 responding, it is smart enough to shut off the water supply automatically. Flo by Moen can accurately measure flow, pressure, and temperature with three sensors.

What Makes Flo by Moen the Best Consumer Option?

There are other leak detection systems on the market, but most water meters have trouble detecting small leaks. The problem with relying on a solution is that small leaks can become big problems. You could look at significant mold issues if the leak occurs behind walls. Aside from that, small drips can account for thousands and thousands of gallons of water over a year. This is why the fact that Flo by Moen monitors water pressure is such an essential component of its capabilities.

Moen calls this proprietary technology MicroLeak, based on the same idea behind the EPA’s WaterSense program, which certifies leak-free properties through rigorous pressure-loss testing (as opposed to via a water meter). Not only does Flo by Moen send your phone alerts, but it will also give you troubleshooting tips to help you isolate the source of any potential leaks.

  1. My Flo device stopped working after 2 years. Inconveniently the warranty is only 1 year. I did the troubleshooting as instructed by Support. No good.
    They suggested that I buy another one. I asked if they wanted me to return it to Support so that they could inspect. They told me to trash it.
    Do NOT buy Flo, defective engineering and/or manufacturing.
