With this easy-to-use leak detector there are no buttons to push, no programming, no wires, and no batteries to insert. Just place the unobtrusive Water Leak Alarm in any potential flood zone: under sinks, next to the washer or water heater, in the basement. When even a small amount of water touches the leak detector, you will be alerted by a loud 95dB alarm. (95dB is about the same loudness as a power mower or police whistle.) When you hear the alarm, you can take action before any major damage occurs. The Water Leak Alarm has a built-in non-replaceable battery that lasts for up to 3 years. You get 3 Water Leak Alarms to use in various locations of your home.
Note: If you test the alarm, simply dry it off before putting it in the area to be monitored.
