The Flo by Moen Smart Water Monitor and Shutoff represents the pinnacle of leak prevention technology. Installed directly on the main water line, this system continuously monitors water pressure, temperature, and flow patterns to detect anomalies that indicate leaks. Its machine learning algorithm establishes a baseline of normal water usage, then alerts homeowners to unusual activity through the companion app. When serious leaks are detected, the system can automatically shut off the water supply within seconds, preventing catastrophic damage. Beyond leak protection, the system provides granular water usage data, breaking down consumption by individual fixtures and identifying wasteful patterns.
Installation typically requires a professional plumber, though Moen provides a Pro Finder tool to locate qualified installers. The system requires both a Wi-Fi connection and continuous power, with an optional battery backup available for power outages. While expensive compared to basic leak detectors, the potential savings from prevented water damage make this a worthwhile investment for homeowners seeking comprehensive protection. Insurance companies often provide discounts for homes with this system installed.
