The water leak detectors are a set of mini alarms that you can place in your basement floor and will sound out an alarm once it detects any sort of water or moisture on the floor. No longer will you have to worry about heavy rain storms, if your sump pump is working properly, a leaky water heater, or if you ate too much Chipotle and clogged up the toilet and let the poop water flow down through the cracks to your basement, the water leak alarms will let you know if there is a water emergency. The water flood detectors fire off an extremely loud alarm at 95dbs that will last for up to 24 hours, come in a set of 3 alarms, and has a non-replaceable battery that will last for up to 2-3 years after purchase.
