This article includes detailed information on the Flo Smart Water Monitor and Shutoff, also known as the Flo by Moen Water Shutoff. It also refers to the Moen Smart Water app, also known as the Flo by Moen app.
The Flo Smart Water Monitor and Shutoff can catch small drips through the Health Test that are too small for the flow sensor to pick up. To find the leak, run a Health Test from the Control Panel. Before you start, verify that all fixtures are closed.
See the ‘Understanding your Health Test’ article on the Flo Support site, or contact Flo Support for step by step instructions.
