Moen Flo 3/4-Inch Smart Water Shut Off Valve 900-001 – Leak Detection & Remote Control

Protect your home with the Moen Flo Smart Water Monitor and Shutoff

Designed for the main water line, this compact device learns your home's water usage and stands guard 24/7. It can detect small leaks, running fixtures, and unusual pressure or temperature changes, offering a proactive layer of protection without constant monitoring.

How it helps you stay in control

Live data from the Moen Smart Water Network App lets you see water flow rate, pressure, and even temperature in real time. If something looks off, you’ll receive a notification—through the app, plus optional phone calls and emails—so you can act quickly, from anywhere.

• Automatic shutoff when abnormal activity is detected to help prevent damage
• Remote control of water flow from anywhere with an internet connection
• FloSense technology to tailor protection based on your home's usage

Remote protection, offline resilience

The system can automatically shut off if you’re away or unable to respond. If your Wi‑Fi drops, the device stores learnings locally and continues to safeguard your home until connectivity is restored.

The Moen app is free—there are no subscription fees—and the device is designed for simple installation. Everything you need is included in the box, and professional installation is recommended to ensure optimal setup.

• In-the-box essentials for 3/4" to 1-1/4" pipes (model 900-001)
• Compatibility with Alarm.com, Ring, Google Assistant, and NICE
• Clear status and alerts for leaks, left-on fixtures, and temperature risk

Real-life scenarios

Imagine you’re on vacation and a small leak begins. The Flo system detects it, notifies you, and can automatically shut off to limit water loss. At home, you can monitor and respond using the app, giving you peace of mind without constant worry.
