The Korky leak detector tablets are designed to help you identify if your toilet has a leaking flapper. As the tablets dissolve, they turn the water blue. Simply drop a couple leak detector tablets into the back of your toilet tank and wait 15 minutes. If the water in your toilet bowl has any traces of blue water, you have a leaking flapper and it signals that it's time to replace it. Easy to use, the LIT117 includes: (2) Leak detector tablets and (1) Instruction.
