Moen 900-002 1-1/4 in. Flo Smart Water Monitor and Shutoff

Brand: Moen | SKU: 900-002

Product Overview

The Moen 900-002 Flo Smart Water Monitor and Shutoff adds whole-home water monitoring and automatic shutoff protection to a 1-1/4 in. or smaller water line. Installed inline on the home’s main water supply, it monitors flow, pressure and water-use patterns so homeowners can spot unusual activity before a small plumbing problem becomes a larger source of water damage.

FloSense technology learns normal household water use and can identify abnormal flow, including very small leaks. Alerts can be delivered through the Moen Smart Water App, and the valve can shut off the water automatically when the system identifies a serious problem. Homeowners can also view water-use history, pressure and flow information and remotely control the water supply through the app.

This model is a strong fit for homeowners who want proactive leak protection rather than relying only on moisture sensors placed near individual fixtures. Wi-Fi and nearby AC power are required, and professional installation by a licensed plumber is recommended.
