I bought 2 of these after my basement window well filled with water during a rain storm and the water had no where to go so it came in to my basement! I learned that night that I had no drain system for my windows. I placed one under the window and one under my kitchen sink incase my dishwasher or sink ever leaked. Last night, the alarm went off after we had all gone to bed when the counter mechanism from the disposal was clogged and the water from the dishwasher started to shoot out the top of it. We would have slept through the entire cycle and had a way bigger mess to clean up otherwise. The alarm was loud enough to wake me up and my husband heard it from down in the basement. I am now buying a few more of these for the bathroom sinks and my hot water heater which is next to my basement sink - 2 birds with 1 stone. We check the batteries 2X/year at the same time as our smoke/fire alarms.
