Toilet Leaks

Listen and watch for toilet leaks. To test for “flapper” leaks, put a coloring agent–food coloring, egg dye or other water-soluble color–in the toilet tank, and check to see whether any of the color leaks into the toilet bowl within ten minutes. Flapper replacement is the most common remedy for such leaks. Check float ball assemblies for corrosion of metal components that may prevent the shutoff of water refilling the tank so that it runs over into the overflow pipe; such leaks won’t show in a dye test but can cause great water loss.
