This system is for homeowners who want to stop water damage before it starts, like protecting a finished basement from a burst pipe while you're away. It's not just a leak detector; it's your first line of defense against costly repairs.
Installed at your main water line, it shuts off the supply within 20 seconds of a leak. The dual sensors adapt to your home: use the wireless one in a humid laundry room without false alarms, and place the wired sensor under a sink for instant alerts. You get a notification before water spreads, letting you act fast.
Setup is straightforward with basic tools, fitting common pipe connections. It works with up to eight wireless sensors, covering high-risk areas like bathrooms and kitchens. Keep it plugged in to maintain automatic protection, giving you reliable whole-home security.
