There is nothing worse than water damage. The Flood Buzz Water Alarm will warn you when there is a leak in your home before it’s too late! These small, inexpensive, and loud alarms have two metal prongs on the bottom of each and when water comes in contact with the metal prongs, it closes the circuit and sounds an up to 110 dB alarm. Since the Flood Buzz Water Alarm comes with an integral battery that lasts for up to three years, all you have to do is place the unit next to any potential leak source. The units are maintenance free until you replace them. You get three alarms in the package.
