1,001 – 5,000 gallons$0.60 per 1,000 gallons
5,001 – 20,000 gallons$3.10 per 1,000 gallons
20,001 – 40,000 gallons$6.19 per 1,000 gallons

If your household is only within the second price tier, you would save $125.00 per year with a Water Efficient Toilet.  Water savings alone will pay for a new toilet in only a few years.

Additionally, the new toilet is far less likely to have problems.  A typical problem of an older toilet is when the float does not shut the water off completely once the tank is full. A “silent leak” in a toilet wastes 7,000 gallons of water a month.  This leak wastes 84,000 gallons of water per year, or $260.oo.

 $385.00 a year for an old toilet.

In less than 2 years, it’s easy to see how an old toilet can cost you more than a purchasing a new one, and you still have the old toilet.   If you are flushing your money down the toilet, perhaps it’s time to replace your toilet.
