Leak Puppy Electronic Water & Flood Leak Detector — 6 Pack Alarm Sensors, Detects as Little as 1/32" of Water, Loud Overflow Alert

Catch leaks before they become costly — each Leak Puppy electronic sensor is triggered by as little as 1/32" of water. Use several units to protect vulnerable spots around the home, placing them wherever a leak might start. When moisture is detected the unit emits a loud alarm that can continue for weeks while wet. A continuous warning tone also sounds when batteries are low, so you won’t be caught off guard.
