If you really want to save water, experts say you need to stop using the toilet as an ashtray or wastebasket. Some people flush away tissues and other bits of trash in the toilet. Using a wastebasket will save all those gallons of water that otherwise go wastefully down the drain. Most toilets installed before 1980 use 5-7 gallons of water per flush. Toilets installed between 1980 and 1993 use 3.5 gallons per flush. Toilets installed since 1994 use 1.6 gallons. If you think about it, 1.6 gallons is still a big improvement, but that’s a lot of water for one flush.
Does your toilet ever make noises when it is not in use? A toilet with even a small leak can greatly increase your water bill. To check your toilet for leaks, put a few drops of food coloring in your toilet tank, and wait ten minutes. If, without flushing, the color begins to appear in the bowl, you have a leak, which should be repaired immediately.
Plumbers say there is no definite answer on how long the parts in your toilet tank should last? Replaceable parts such as flappers and washers or seals inside the refill valve may last several years. However, factors such as water treatment processes, toilet bowl cleaners, and high water pressure can cause parts to disintegrate much sooner.
