Upgrade the reliability and flexibility of your Moen Flo Smart Water Monitor & Shutoff System with Moen’s Smart Home accessory line. These accessories—AC Adapter (920-002), 25' DC Extension Cable (920-003), and Battery Backup (920-008)—enhance installation options, ensure uninterrupted protection during power outages, and expand power routing flexibility. They are designed specifically for Flo by Moen systems and engineered to maintain safe, continuous operation for your home’s smart water protection.
The backbone of the Flo Smart Water Shutoff is continuous power to the valve, and the AC Adapter ensures a stable, reliable connection. Whether you are installing indoors in a mechanical room or outdoors in a protected space, the 920-002 supplies low-voltage power directly to the Smart Water Shutoff. It is purpose-built to handle everyday use and accommodate high-performance monitoring, including daily micro-leak tests, real-time flow analysis, and system learning via FloSense technology.
When paired with the Moen Smart Water App, homeowners have full control of the valve—from shutting off the water remotely to reviewing live water usage and alerts. The AC Adapter ensures that power remains stable so the system can provide continuous data collection and alerting.
Many homes, cottages, and commercial mechanical rooms do not have a power receptacle located directly beside the main water line. The Moen 25' DC Extension Cable solves this common challenge. Designed exclusively for Flo Smart Water Shutoff systems, this extension cable increases installation flexibility without the need to relocate pipes, electrical outlets, or equipment.
You can connect up to four extension cables together, giving you up to 100 feet of total cable length. This is especially beneficial in mechanical rooms, crawl spaces, or retrofit installations where power is not immediately accessible. As a low-voltage compliant component, it maintains electrical safety throughout the wiring path.
The Moen Battery Backup is the ultimate failsafe for your home’s water security. In the event of a power outage, storm, or unexpected interruption, the backup battery allows your Flo Smart Water Shutoff to continue operating for up to four hours, enabling the device to:
Detect leaks
Monitor pressure and flow
Auto-shut water off if needed
Installation is simple: it mounts to the wall and plugs directly between the Flo Smart Water Shutoff and its power cord. No pairing. No complicated setup. Just uninterrupted protection when you need it most.
The backup unit uses next-generation Lithium-Ion technology, designed and tested for long-term reliability. It is rated for indoor environments and carries Moen’s one-year limited warranty for peace of mind.
When the Flo Smart Water Shutoff is installed without these accessories, the system depends strictly on available power and cable reach. These three accessories remove those limitations:
| Accessory | Purpose | Key Benefit |
|---|---|---|
| AC Adapter (920-002) | Primary power supply | Provides stable power for the device |
| 25' DC Extension Cable (920-003) | Extends power reach | Allows flexible equipment placement |
| Battery Backup (920-008) | Emergency power | Keeps system active during outages |
Together, they ensure your water security system remains online, accessible, and operational under all conditions.
Homes with mechanical rooms or hard-to-reach power outlet locations
Cottages and seasonal properties that need backup protection
Smart-home users who want to eliminate risk and maximize data uptime
Retrofits where power access is limited
Protect your home or investment property knowing that power interruptions and layout limitations won’t compromise water safety.
