Today's question: How can I tell if my toilet is leaking?

"Plain Talk" answer: To check, put a few drops of food coloring in the tank, wait about 15 minutes and look in the bowl. If the food coloring shows up there, the tank is leaking and should be fixed. Toilets should be checked for leaks every year.

Some utilities give away conservation kits with food coloring tablets, flow restrictors and plastic bags to fill with water and put in toilet tanks.
