Review on Leak Puppy Electronic Water Alarm - Advanced Leak Detector - Detects Water as Thin as 1/32 inch - Set of 3 Water Alarms by Frank Chinchilla

The alarm is very sensitive and loud enough that we found it in the basement from the first Floor can hear the house. The battery life is also good. Thanks to this alarm, we discovered a leak in our water heater when it was just a trickle. The maintenance engineer noted that he was rarely called this early for a water heater failure and was more used to working in recently flooded basements. I recommend her to everyone I know. They are incredibly cheap compared to the water damage they can prevent.
