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.

Full awareness over water usage!

The combination of the Moen smart shutoff / water meter and leak detection gives me full awareness over my water usage. That is very important to me because I am using mainly rain water in my house. The reason, why I only give 4 stars instead of 5, is because there are a few little things in the app, which could be improved IMO. First during setup it asks wether I am on city water or a well, rain water is not an option. Second, it does not differentiate between appliances. Dishwasher and washing machine both fall in the same category despite different water usage. Third, There is no option to customize water using appliances. I would like to distinguish between different showers because I use different shower heads with different gpm ratings. Would be interesting to see the difference in the long run. Overall a very nice setup! UPDATE after 3 months of usage: I am still 4-star happy with this product. It just gave me a warning, that it detected an unusual event, when I took a longer-than-normal shower. Warned me, that it would shut off the water in 5 minutes. HA! Watchdog! Like it!

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.
