Frequently Asked Questions

How does the Smart Water Shutoff categorize a catastrophic leak which shuts off water?

The Smart Water Shutoff employs artificial intelligence algorithms to learn the normal hydraulic behavior of each installation. Flo’s security module analyzes telemetry in real-time to determine if system conditions are consistent or anomalous (warranting alerts / shut-off action).

How does the health test work?

During the Health Test, the Smart Water Shutoff will close its valve, preventing any water supply from influencing your home. While the water is shut off, Flo will monitor the stability of the water within your pipes for the next several minutes. If there is very little to no pressure change, you will pass your test.

What happens if the power goes out, will I still have water?

Yes, the Smart Water Shutoff does not turn your water off in the event of a power outage. Should you wish to turn off the water to your home, Flo recommends you use the Flo by Moen app. If the power is out (or in case of other emergencies) you may use the green manual knob on the Smart Water Shutoff to turn your water on or off.

My power outlet is too far to reach the Smart Water Shutoff, is it okay to use an extension cord?

Flo does not recommend the use of indoor extension cords in outdoor environments. If an extension cord is needed, you may purchase the Flo Extension cord through our online store or by clicking this link.
