If a leak is detected, you'll receive an alert through the app, and the Flo Shutoff can automatically shut off your water to prevent a minor leak from causing major damage.

FAQs

How is the Flo Shutoff different from other leak detection solutions?

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.

What does in-line installation mean?

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.

Can I install the Flo Shutoff on my own?

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.

Will the Flo Shutoff work without Wi-Fi?

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.

Will the Flo Shutoff protect against flooding from the environment?

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.
