About This Product

The Moen Flo Shutoff installs on your home's main water line to monitor flow, pressure, and temperature 24/7, and automatically shuts off your water if it detects a leak, before it causes serious damage. Most water devices wait for a leak to happen, then send you an alert. The Flo Shutoff works differently. It proactively runs daily MicroLeak tests to find small drips, high pressure, and freezing conditions before they cause damage. When something is seriously wrong, it doesn’t just notify you, it automatically shuts off your water. A third-party LexisNexis study found homes with a Flo Shutoff saw up to a 96% reduction in water damage claim events. Stay in control from anywhere with the Moen Flo App, and add a FloProtect plan for extended warranty coverage and insurance deductible support. Because the Flo Shutoff installs in-line on your main water supply, professional installation is recommended. Water damage is the most underestimated threat inside a home; more common than fire and more costly than theft. Moen Flo exists to change that. We prevent loss, one drip at a time.

Highlights

  • Control from anywhere: the Moen flo app keeps you connected to your home water 24/7, so you can monitor, manage and shut off your water from anywhere in the world
  • Intelligent protection: flosense technology learns your home's unique water patterns, getting smarter with every use to identify abnormalities like running water or small leaks before they become a problem
  • Water damage happens, Moen flo prevents it: water damage is the most underestimated threat inside a home; more common than fire, more costly than theft, Moen flo exists to change that, we prevent loss, one drip at a time
  • Professional installation by a licensed plumber is recommended

  • Internal sensors monitor the actual water moving throughout your home and distinguish between typical water usage and a leak or burst pipe, unlike competitive products that use ultrasound technology to listen to the water

Questions & Answers

Will this tell you water usage over a period of time for the whole home?

Answer This Question

Hello ErHa and thank you for your interest in Moen products. The Moen Flo 1 in. Shutoff Whole-Home Leak Detector and Automatic Water Shutoff Valve with Brass Fittings water usage by day or week can be viewed in the app; the total consumption for 12 months can be accessed on the Flo website. Water Usage History feature is not a substitute for your water meter reading, as your Moen Flo Shutoff water reading and water meter reading operate differently. For example, depending on the location of your installations on the water supply line, your Moen Flo Shutoff and water meter may not cover the same water usage. Should you have additional questions, please feel free to call us at 800-289-6636. We are available Monday through Friday from 8:00 am - 7:00 pm (EST).

                  Moen Flo is a gamechanger. I bought it for our new house for peace of mind as an insurance policy against flooding from burst pipes in the Ohio winters. Only after installing it did I realize it's actually a whole-house water management and intelligence system. I'm continually amazed at the insights it is able to offer and its ability to discern a unique 'signature' for each plumbing appliance by its water-usage pattern after only being installed 3 weeks ago. We're living in the future!

                      Premature Failure + Weak Warranty = Not Worth It
                      I installed the Moen smart water shutoff valve about 2–3 years ago expecting long-term reliability. After all, this is fundamentally a water valve—something that traditionally lasts decades. Out of nowhere, the system started reporting zero flow, even though water is clearly running. I contacted Moen support, and to their credit, they acknowledged a common issue and sent a replacement turbine sensor. I installed it, but the problem persisted. After additional troubleshooting with support, they were unable to resolve the issue and ultimately told me the unit is out of warranty (only 1 year)—so my only option is to buy a completely new system. That’s unacceptable. Let’s be clear: This is not normal wear and tear. This is not a consumable product. A water shutoff valve should not become e-waste after a couple of years. What’s especially disappointing is that the failure appears tied to sensor/electronics reliability, not the core plumbing hardware. So instead of a durable, long-term solution, you’re effectively buying into a short lifecycle tech product—with no meaningful support after year one. Bottom line: Great idea in theory, but poor durability and a weak warranty make this a risky investment. I cannot recommend a product that fails this quickly and leaves the customer with no real support.

                      Hello Andy. Thank you for sharing the details of your experience with the Moen Flo Shutoff and the troubleshooting steps you have already taken, including replacing the turbine sensor. The Flo Smart Water Monitor and Shutoff (Moen Flo Shutoff) includes a 1-year limited warranty that covers manufacturer defects. If you are experiencing “zero flow,” we recommend inspecting and cleaning the internal flow sensor and turbine, as debris or installation residue can sometimes cause the sensor to stop registering flow. If you have already completed the recommended steps and the issue persists, the Moen Flo Shutoff may need to be replaced. If you are having any issues or have any questions, we recommend reaching out to Moen Smart Water Support for technical and warranty assistance at 1-800-289-6636, option 8. Our business hours are Monday through Friday from 8:00 am - 7:00 pm Eastern Time. Moen

                          Flo Water Monitor Shutoff should be in every home
                          [Employee of moen] I feel secure knowing I will be notified by any water leak and the Moen Flo Smart Water Monitor & Shutoff will shut off my water at the point of entry in my home until I can investigate the leak. I also have the Moen Flo Water Detectors under every sink and other locations throughout my home. They communicate to me through the Moen app and to the Flo Smart Water Monitor & Shutoff. It is also a great way to monitor your water usage for conservation.
