See why homeowners trust the Flo Shutoff for whole-home leak protection.

We experienced an indoor flood that required six months of repair to our home. Our contractor recommended installing the Moen Flo, and we could not be happier… Wish we had installed the Flo in our home years ago — it would have saved us from our flood!

Verified Purchase

We have a number of properties and all with different alert systems for water leaks — honestly Moen wins!

Verified Purchase

My Moen Flo works well and has kept me informed about our water usage. We also inadvertently tested it when we left a soaker hose on for two hours. The Flo turned the water off to the whole house and sent us a warning so we know it works.

Verified Purchase

Makes me feel very safe that my house won’t flood. I’m telling everyone to buy one.

Verified Purchase

This is one of the best products I’ve ever bought. We love the peace of mind we get from having our water monitored for any leaks. With it showing the water usage, we can now make better eco saving choices.

FAQs

Leak detectors can sense moisture in specific areas of your home while water monitors can identify leaks and measure water pressure through sensors on the outside of your water line. However, neither of these products offers a way to proactively prevent water damage.

The Flo Shutoff is installed in line to monitor the pressure and flow rate of the water moving through your home’s pipes, offering water monitoring, leak detection and shutoff capabilities all in one device.

In-line installation means that the Flo Shutoff is installed on the main cold water supply line for your home, which requires removing a section of the water pipe. Visit our Help Center for more information and to view our guided installation video.

The Flo Smart Water Monitor and Shutoff is installed on the main cold water supply line, which typically enters your home through your garage, basement or an exterior wall. Since the Flo Shutoff is a precision-engineered device and installation requires removing a section of your main water pipe, this is considered an advanced project, so we recommend using a plumbing professional for installation.

Wi-Fi is required for full functionality and the Flo Shutoff will only operate under the 2.4GHz frequency range, which provides longer range connectivity compared to the 5GHz. However, if the device loses its connection, it will continue to protect your home. The Flo Shutoff stores the latest learnings locally, allowing it to continue safeguarding your home until the Wi-Fi connection is restored.

While the Flo Shutoff can prevent flooding caused by leaking pipes, fixtures or appliances, it cannot protect against flooding due to external environmental factors, like heavy rains, an overflowing sump pump or a leaky roof.
