Water damage from a slow leak can cost thousands before you even notice it. The LEVEL SENSE Floor Water Sensor solves that problem with a straightforward design: a 6-foot detection cable that connects directly to most standard home security systems. No hub, no app, no monthly fees. Just a physical sensor that triggers your existing alarm when moisture hits the cable.

The sensor itself measures just 2.5 inches long and half an inch thick. It’s built with stainless steel contacts and ABS plastic housing. The 0.5 amp current rating means it integrates cleanly with wired alarm panels and security controllers. Mount it behind your water heater, under the washing machine, or near the utility room sump pit. The included screws let you secure the unit to the floor or baseboard. The cable snakes out flat, covering a 6-foot radius from the sensor body.

One limitation: this sensor requires a compatible alarm system or controller to function. It doesn’t sound an alarm on its own. If you don’t have a wired security panel, you’ll need a LEVEL SENSE hub or similar input device. For anyone with an existing home security setup, this is a simple, reliable way to catch leaks before they become floods.
