About the Flo by Moen 1-1/4" Smart Water Valve
Prevent catastrophic damage
Prevent catastrophic damage
When I bought my first home, my stepdad told me "water is your enemy." I already knew that after dealing with burst pipes in my previous two apartments, but I took it to heart with renewed vigor knowing I'd be liable for all the damages now. There are a lot of ways water can cost you as a homeowner, and Flo by Moen aims to protect you from a big chunk of them.
Flo alerts you to small problems before they become big problems.
This small device attaches to your main water line and constantly monitors the pressure, temperature, and flow of water into your house. That way, it knows when something is amiss. And if Flo detects a drastic change, it will shut off the water before it can devastate your home.
Stop the nickel and dime stuff, too
Flo also runs a health test on your system every night and can detect leaks as small as one drop per minute. You might have no idea those leaks even exist, but they are an early indicator of potential pipe bursts later. And they cost you money on your water bill every month.
With Flo and its companion mobile app, you can stay on top of even small leaks before they turn into big problems. The app lets you track historical water usage and set goals for your family's water consumption. You can also turn your water on and off from wherever you are.
The Flo by Moen system has three modes — so you get the right kind of monitoring and response for every situation. Keep it in "Home" mode for normal day-to-day use. Select "Away" when you'll be gone for an extended period of time. In this mode, Flo will respond more quickly to protect your home when abnormal events are detected. Engage "Sleep" mode when you're intentionally using an irregular amount of water. Flo will not run its normal tests in this mode — so you won't get urgent notifications when you're trying to fill the pool or water your garden.
"Alexa, ask Flo how much water I've used this month"
Flo by Moen works with Amazon Alexa and Google Assistant (sold separately), so if you want to monitor your water usage or find out about any pending alerts, all you have to do is ask.
Flo by Moen comes in two sizes. The 3/4" version is intended for water mains 1-1/4" and smaller, while the 1-1/4" version is used for water mains 1-1/2" and smaller. The optional battery backup works with both versions and will keep your Flo powered for three or more days durage power outages.

More details on the Flo by Moen 1-1/4" Smart Water Valve
Overview: Flo by Moen is a smart water valve that monitors the flow of water into your home. It can help save you money by monitoring and controlling the water usage in your home. It can also protect your home by detecting, and informing you of, a water leak that can potentially cause tremendous damage. You can keep track of your household's water usage on the Flo by Moen smartphone app, and receive notifications in case of a leak detection. The Wi-Fi-controlled Flo by Moen kit includes the monitor/detector device, power supply, and installation parts. FloProtect is an optional subscription-based protection plan that gives you extra data, proactive monitoring, and an extended warranty. This kit is designed for systems with 1-1/4" main water lines.
Note: A version for 3/4" water lines is also available.
Leak Detection: Water damage in homes is a leading cause of preventable homeowner's insurance claims every year. Flo by Moen continually monitors the flow of water into your home, and can detect even a tiny leak (as small as one drop per minute), and send a notification to your smartphone through the Flo by Moen app. The app give you the ability to shut off the water remotely from your smartphone to minimize the damage. The system can also send text messages, emails, and phone calls. An 8mm Allen wrench is included for manually shutting off the water directly at the Flo device.
Water Monitoring: Flo by Moen monitors your household's daily and monthly water consumption. On the Flo by Moen app, you can see the flow rate, pressure, and water temperature in real time. The app's dashboard displays a bar graph of the water usage in your home by the hour, so you can view the peak times. Each day, Flo by Moen runs a Health Test to identify if there are potential small drips in the plumbing system. By monitoring your water usage, you can be proactive about saving water by setting water consumption goals. You can also prevent surprises on your water bill, and avoid catastrophic damage while you're on vacation.
Installation: The Flo by Moen smart water valve installs on the main water line (3/4" line for this model) after the manual shutoff and pressure reducing valve (if you have one). If your home has a well system, you should install the device after the well pressure tank with a 100 mesh or finer Y-strainer. The device operates on Wi-Fi (802.11b/g/n, 2.4GHz band), and requires a working Internet connection. A 100-240V AC outlet is required for plugging in the AC adapter. The Flo device is safe for outdoor use, and is IPX5 water resistant (but not intended to be submerged in water). If the Flo device is installed outside, a weatherproof AC receptacle must be used.
Note: It is recommended that Flo by Moen be installed by a licensed plumber or installer.
Flo by Moen App: The Flo by Moen app gives you control over the device, and helps you conserve water, save money, and keep your home protected. From the app, you can monitor your daily and monthly water consumption, run diagnostic leak tests (manually or automatically), and remotely turn your water off or on with a tap of your finger. Even while you're away, Flo by Moen monitors your water flow, and, if it senses a major problem, can automatically turn the water off. The Flo by Moen app is available on the App Store for iOS devices running version 9.3 or later, and from Google Play for Android devices running 4.4 and up.
Smart Home Integration: Flo by Moen integrates into other Smart Home devices, including Amazon Alexa and Google Assistant. You can obtain information on your water usage, get alerts, or remotely turn the water on or off using voice commands with your favorite digital assistants. In addition, you can use IFTTT (If Then, Then That) applets to connect with other useful services or smart home devices in the IFTTT platform.
Health Tests: Once a day, Flo by Moen automatically performs a Health Test to identify potential problems in your plumbing system. Using MicroLeak technology, small leaks that often go undetected can be discovered before catastrophic water damage occurs. During a Health Test, the Flo device shuts off the water to the home and monitors the pressure in the system over a period of time. Constant pressure is a sign that your plumbing system is in good condition. However, if the pressure decays, it could be an indication of a leak, or other problem in the system. Health Tests are typically run at a time of inactivity, such as overnight, when water fixtures are not being used. If someone needs to needs to open a fixture during the test, the test is automatically aborted, so there's no interruption in water service. The Health Test will simply be rescheduled at a later time. Health Tests can also be run manually from the Control Panel on the Flo by Moen app.
FloProtect: FloProtect is an optional subscription-based protection plan for Flo by Moen users. For $5.00 per month, FloProtect offers the following:

Optional Backup Battery: An optional Backup Battery Module is available to power the Flo by Moen device in the case of a power failure. This Lithium-Polymer rechargeable battery (10.8V, 13000mAh, 140.4wH) acts as an uninterrupted power supply, to keep the Flo by Moen device functioning normally for approximately three days. The battery backup is connected in-line with the Flo device's power supply. During normal power, line supply operation power is transmitted directly to the Flo device. If power is interrupted, the module instantly switches to battery mode to keep the Flo device operational. When line power is restored, the operation reverts to main line supply, and the backup battery is recharged.
