What, besides leaking faucets, could contribute to a high water bill?
A leaking toilet could be the problem. First, check the water level to make sure that water is not overflowing the tank into the overflow pipe. If water is running into the overflow, adjust the fill valve to stop the flow approximately one inch below the top of the overflow tube or to the water level mark stamped on the side of the tank. Another test is to put a few drops of food coloring into the tank to test the flush valve mechanism. If the water in the bowl changes color within 15 minutes, this is an indication that water is leaking into the toilet bowl and that the ball or flapper needs to be replaced.
