If your bill is high, be sure to check faucets for small drips and listen to toilet valves to see if they run unexpectedly. You can also check your toilet flapper valve for a leak by placing a few drops of food coloring in the tank itself. If the water in the bowl changes color prior to flushing, you have a leak. It is also not uncommon to find leaks in service lines entering your home. Seek assistance from a plumbing professional or your local home improvement center to fix all such leaks.
