Leak Detection Toilet Dye Tablets are used to rapidly identify a leaky toilet. Simply place the Leak Detection Dye Tablets into the toilet tank, and if blue water appears in the bowl, you have a damaged flapper that needs to be replaced. A slow toilet leak can waste thousands of gallons of water per year and drive up your utility bills.
