It worked for me

I had a flood once from a broken pipe under the kitchen sink. There was almost $28,000.00 worth of damage. Don't want that again. Here in Nevada it is required to have a metal tray under your hot water heater and piped off to a safe location. I installed 3 of these water alarms. 2 under sinks and one for the hot water heater. I used the remote wire so I could have the sensor at the bottom of the tray and mount the alarm at eye level. I did this so I could change batteries easier. I sure do sleep a lot better now.. Good investment.

Save $$ with First Alert Water Alarm

My dishwasher leaked causing major damage to the drywall in my kitchen island. It was costly and messy to clean up. This handy inexpensive device will alert me before it happens again. EASY TO INSTALL and sounds loud alert even when just touched to a damp sponge. GREAT VALUE

Hook up additional wires in parallel and cover multiple areas (close by) with one unit. I am covering two a/c air handlers in pans along with a humidifier.
