This adds to the cost of water and sewer utilities and adds to your water bill. Retrofit all household faucets by installing aerators with flow restrictors to slow the flow of water. Check for toilet tank leaks by adding food coloring to the tank. If the toilet is leaking, color will appear in the toilet bowl within 30 minutes. Check the toilet for worn out, corroded or bent parts.
Most replacement parts are inexpensive, readily available and easily installed.
If the toilet handle frequently sticks in the flush position letting water run constantly, replace or adjust it. Install a toilet dam or displacement device such as a bag or bottle to cut down on the amount of water needed for each flush. Be sure installation does not interfere with the operating parts. When purchasing new or replacement toilets, consider low-volume units which use less than half the water of older models. In many areas, low-volume units are required by local building codes.
