Peace of mind

I live been wanting to purchase the Moen for quite awhile but the plumbers where our second home is located are so busy they don’t respond to phone calls. I was able to finally find a guy that sold me the Moen product and his brother and law installed the system. I’ve had it now for about 4 months, this thing detects very small leaks like someone not shutting off the outside valve completely. I didn’t realize when we purchased this second home that my water pressure was so high and when we installed this valve it immediately told me my water pressure, the plunger out on a water reducing valve and now I don’t have to freak out that the pressure is high. We live 1000 miles away from this house and I can say without a doubt this has relieved my anxiety about coming there only to see water gushing everywhere with mold. Great product and it has told me when the people who maintain my hot tub are refilling it and will earn to shut it off. If you want peace of mind buy this product it’s an excellent unit.

Fresh water is a valuable resource in California. This system is an invaluable tool to manage its usage. I have used this app (with pro extensions) for a few weeks now. It it way better than expected. I have identified a number of issues around the house - dripping valves, irrigation overwatering etc. Also easy to determine flow rate for each fixture in the home including individual irrigation zones which I have found very useful.
Very convenient way to shut off water for repair or emergency.
System has warned me a few times when usage is longer than normal and about to turn water off. Leak detection is genius particularly with our aging radiant floor heating (susceptible to undetectable small leaks). Usage analysis by fixture, although a tricky goal, could imo be better but feel confident the smart software engineers at flo will be improving this feature over time.
Bottom line - don’t regret the purchase of this valve. If you care about how much water you use this really does help.

Flo is simply indispensable! Whether you have a “smart home” or not, you should have Flo as a sentinel. Water damage is horrible, whether a sudden discharge or an insidious leak. Flo monitors for both. Daily health checks monitor for leaks (Flo alerted me to a leak that left unnoticed would have caused hundreds of dollars damage). If a sudden, unexpected water flow occurs, you will get a notice, and the water to your home will be shut off temporarily.

Flo is easy to install if you are handy, and inexpensive to install if you use a plumber. Tech support is tremendous, and the peace of mind Flo gives you is invaluable.

Just get one, and start sleeping better!
