Airthereal Water Leak Detectors 2-Pack, 120dB Adjustable Audio Alarm Sensor, Sensitive Leak and Drip Alert, for Kitchen Bathroom Basement (Battery Included)

These detectors are very handy to have. There has been quite a bit of flooding recently so having a few of these in the basement gives an added peace of mind and stops us from checking it as often. They also give you a tool that helps open them up to install a battery, very handy. Jennifer. Middletown, CT. Tue Jul 25 2023
