If Your Plumbing Is Old, You Need Water Leak Alarms Beth Snyder April 5, 2011 These could very well be the cheapest, easiest way to save hundreds if not thousands of dollars you can get. Of course, if you can afford a plumber to take care of the problem, you’re all set, but if you’re like me that’s not an option unless something horrible happens. And by then it’s too late. Enter the Water Leak Alarm. They come in a set of three, and are dirt simple to operate. Simply place them near a potential source of water leakage such as your washing machine, dishwasher, toilet, or kitchen sink, and forget about them. If they detect even a tiny amount of water where it shouldn’t be, they emit an ear-piercing 100db alert for up to 24 hours. The internal batteries are not replaceable, but are supposed to last up to three years. A set of three alarms is only $19.99 US. Source: Oh Gizmo! Share This With The World!
