It worked - imagine that.
"A product that actually works. It went off by accident. I had it all rigged up and then had to change the hoses. In the process of disconnecting hoses, water came down and got the cotton swap wet and it immediately swelled up, tripped the shut-off valve and then left a 3" snaky looking thing in the tray. So, we purchased 4 more plugs just to have a stockpile. Our old unit only had an audible alarm which worked, but not good if you are not home to deal with the issue."
