This GE Water Leak Detection Alarm can save your home from possible disaster and you from costly bills. It’s a water alarm that warns you of the first sign of a leak to prevent water and mold damage.
Simply place the alarm in the areas where leaks or water overflow might occur (hot water heaters, toilets, dishwashers, refrigerators, sinks, A/C drip pans, washing machines, bathtubs, wet bars, hot tubs, etc.) and if water starts to puddle, the alarm will alert you.
Battery operated for simple installation and no worries about mixing electricity and water. This could potentially save you thousands in potential damages!
Note: I can't find this exact model on Amazon, but did find this similar GE leak detector for $18.
