Smart leak sensors and automatic shutoff valves can prevent catastrophic water damage. Compare Flo by Moen, Phyn, and Honeywell options.
Smart leak detectors alert your phone when moisture is detected — buying you minutes to hours before catastrophic damage. Whole-home shutoff systems (Flo by Moen, Phyn Plus) monitor water flow and automatically shut off the main supply when abnormal usage is detected.
Install sensors near water heaters, washing machines, under sinks, and behind toilets. Whole-home systems cost $500–$900 installed but can prevent $10,000+ damage events. Many insurers offer discounts for leak detection devices.
