Description

Bring smart plumbing to your home with the Flo Smart Water Monitor and Shutoff. The Smart Water Monitor and Shutoff is a smart home water security system that provides 24/7 protection by monitoring for water leaks—some as small as one drop of water per minute—and other vulnerabilities. Designed by plumbing and tech industry professionals, Flo Smart Water Monitor and Shutoff is installed on the main water supply line of the home. You can see live water use through the Moen Smart Water Network App, including water flow rates, pressure, and even temperature. If the Smart Water Shutoff detects an issue (e.g. high pressure, freezing water, or a small leak), a water sensor alarm will alert you through the app to assess the issue before it causes costly damage. If there is a catastrophic failure, like a burst pipe, you will be alerted in the app allowing you to shut the water off remotely—no matter where you are. If you fail to respond to the alert or are on vacation, the device can be set to automatically shut off water to help limit damage and loss. The smart water app notifies you of abnormalities to remotely turn off the water from the Moen Smart Water Network App, or the device can be set to automatically close the valve to help prevent catastrophic damage. In addition to leaks, the device will notify you if it senses a fixture has been left on or if temperatures have dipped too low and pipes are at risk of freezing. The app is free, with no fees or subscriptions required. Should the Wi-Fi connection be lost, the device will still protect the home as it stores the latest learnings locally, allowing it to continue safeguarding the home until a Wi-Fi connection has been restored. Everything needed for installation is included in the box. Professional installation is recommended and takes just a few hours when the home meets installation requirements. The colors of the physical product may vary.

  • Piece of mind; worth the price and monthly fee
Style: Smart Water Shutoff Valve Size: 3/4 inch
I've heard about these for a while and thought it would be a nice thing to have, but never actually bought one, until now. After our neighbor's house flooded for the second time I thought it might be a good idea to have this, since all of these houses were built by the same builder. If they're having that many problems it could be a matter of time before we do as well, as both times their house was severely damaged. I'm not a plumber but have basic skills and had no problems installing the Flo valve. I used a 2" nipple between the Flo and our water filter and a shark bite on the other side to connect into our PEX pipe that comes off the PRV. It took less than an hour to install. Setup was simple and instructions were easy to follow. It took an hour or so for it to realize that it was installed, and then took another week or so to 'learn' our usage habits. Right after installation I began getting real-time data on flow rate, pressure, temperature, and gallons used. The data is pretty cool, but historical data is extremely limited. In the app, you can only get hourly data for the current day and weekly data for the current week. On the website you can only view/download hourly data for the current and prior day, daily for current or past four weeks, and monthly for the past 12 months. We've had the Flo installed for just over two weeks now and had no problems with it. We subscribed to Flo Protect but thus far it still has not identified individual fixtures. A note on that; they say 'we need a couple weeks of data before we can identify fixtures.' I contacted support and they told me it's actually three weeks. I suggested to them that they change their messaging on that to manage expectations. I've seen quite a few people unhappy that they have to pay $5/mo for the Flo Protect plan after paying $400+ for the valve. I have no problem with paying for it. We pay $15/mo for our alarm monitoring after paying around 2k for our system to protect our home. Water can cause severe damage, so I'm good with paying $5/mo to monitor that since it's probably more likely to happen than a break in when you think about all the places plumbing could fail and the extent of damage it can cause. Sure, insurance will probably pay for most of the repairs, but as I sit here listening to them jack hammering up the hardwood floors a couple doors from me for the entire day and watch all the various work trucks coming and going, I think of the inconvenience of it all. Overall I give the system a 4 star rating because availability of historical data is quite limited and I'd like the ability to download detailed hourly or daily data for a large period of time into Excel to perform more detailed analysis. If the data was more available I'd give it a full 5 stars. Support through the water concierge chat is excellent but anything I've sent via e-mail has gone completely unanswered, so I recommend using the chat. Today I purposely left our kitchen faucet on at a trickle while I was eating lunch and they called my phone after around 30 minutes to alert me to long water duration. I also got an e-mail about it and an app notification, all of which gave me the option to turn off my water immediately or ignore it. They said if I did not respond they would shut it off in five minutes. I'm pretty sure if a pipe broke and a lot of water was flowing it would have alerted much faster, but I only left the faucet barely trickling. All things considered I think this is a great product and both it and the monitoring are worth it in my opinion. Update 3/8/2020 Usage by fixture finally became available after a little over three weeks of use and I wanted to provide some information on this. My expectations were pretty low for this feature and thus far I would say they may have just barely met them. My thoughts on this are that it would be quite difficult to isolate usage to a particular fixture, since the only data points they could use to identify fixtures would be flow rate and duration and many things could have similar flow rates, not to mention overlapping usage (i.e. you flush the toilet, then go and wash your hands, washing machine could be running while you're taking a shower, multiple people using water, etc.) That being said, it has done a fairly good job in identifying faucets, toilets, and showers/baths, but not always correctly. It has not been able to isolate anything else, such as the washing machine, dishwasher, refrigerator, etc. You do have the ability to go in and reclassify an event but I'm not certain that it learns anything from that or not. I know I changed one it got wrong from faucet to shower/bath and later I looked and it had changed it back. When you look at the event details it only provides the time, duration, and gallons used. It would be extremely helpful if it also provided the flow rate, as that is one of the most useful data points in identifying what fixture may have been using water. I plan to make that suggestion and hope they'll consider implementing it. If I can accurately reclassify events and it actually learns from that then maybe it would get more accurate over time. My overall rating and opinion of the device is unchanged and I still feel it is very useful and provides an extra layer of protection for our home. Update 4/7/2020 Upgrading my overall rating from 4 to 5 stars because they just added expanded access to historical data which was the one thing that I felt was lacking. You can now view data by day, week, month, year, and even by custom date range. Being able to view a custom range is helpful if you want to compare the Flo data to your water bill as you can set it to the same billing period. ... show more

  • Quality Product and already paid for itself!
Style: Smart Water Shutoff Valve Size: 1.25 Inch
Okay, I did a ton of research to find the best water/leak detection system available today. I finally decided to try Flo by Moen, because it had great reviews on everything I could find about Flo. I’m an engineer and I’m very particular about what I buy and I look for mainly quality but also price. I’m also very into smart devices (lights, alarm system, and yes, water leak sensors), but I wanted a whole home leak detection system and auto shutoff! Water damage sucks and we have known many families who came home after being away to find water flowing out the front door and then months of repair and living in hotels, insurance claims, etc. It’s 2020 and it’s about time there is something to prevent disasters! Okay, enough of what you already know... Flo arrived yesterday from Amazon (Friday) and I woke up this morning wanting to install it. Pre-Installation: You know a product is gonna be good when it arrives and the packaging is nice and has clear instructions. Well, I opened the box and the instructions were easy, setting up and account with the app (I use an iPhone) and the app is excellent. Easy setup with the Flo device, WiFi and Flo App. Installation: I thought about installing it myself, but I’m not crazy about working on plumbing. I decided to hire Dutton Plumbing and I called them at 9am and they were here at 11am. I won’t give prices here because I’m not reviewing the plumbing company (although they did a great job and also raved about Flo by Moen). Fair price for a great job and peace of mind that it’s installed perfectly. See pictures. 30 minutes or so later and they were done. They even hung around and helped with app to ensure Flo operation from the app was good. Post Installation: The plumbers left and I started noticing the water pressure increasing... 80,90,100... at 108psi I shutoff the water with Flo and turned off the main city valve. I turned the water on again and the pressure went up again.. see picture showing 83psi... but it was still going up again (I didn’t get a screenshot at 108, but I was so freaked out I didn’t get a screenshot). Anyhow, I suspected I had a bad water pressure regulator because the faucets have been spraying to hard when turned on. I went to a local plumbing supply and got a new regulator and replaced it in 10 minutes. Turned water on and now the pressure is a steady 50psi (or thereabouts) and nice and normal! So, Flo already identified a HUGE issue and now it’s resolved! Crisis averted! I’m super happy with it so far and the app is stellar good! Summary: It’s working and I’m happy to see such a quality device / App combo work so well and this is now by far the smartest and most useful smart device in the house. Support: I did not rate the support because I’ve not need to contact support yet. However, the website and app support pages look good and full of information. Protection Plan: There is $5/month protection plan and I’m on the free 30 days. So, I’m not going to review that portion of the service yet. The next day I woke up at 6am and noticed that 93 gallons of water were used since midnight! I see the water come on every 4 minutes for 5-10 seconds or so... found a toilet that was running (with a leaky flapper valve) wasting water! I shut off the toilet and fixed went to Home Depot for parts and fixed it. Flo saved me again! I don’t usually rave about a product, but I have to say this thing is great! Just to note, Flo did not alert me that there was a toilet wasting water, I just noticed the number of gallons used was 93 since midnight. Flo is still in “learning mode” while learning the habits of the house water usage, it takes 7-10 days before Flo will become able to auto shutoff and leak send alerts. For more info on leaning mode search the web for Flo by Moen and learning mode. ... show more
