Frequently Asked Questions

How will I receive a discount from Chubb on my insurance policy?

Once your Flo by Moen Smart Water Shutoff is installed, you can request a letter of verification through the Flo by Moen app to be sent to you digitally. Upon receipt of the letter, you can print or forward to your Chubb agent as proof of protection.

Where can I access the setup and installation guides?

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.
