Toilet Replacement Parts - Water Efficient Toilets - This Old Toilet - Phone: 650-483-1139 ~ 800-658-4521

 Do you know how many high-efficiency toilets we have in the U.S., or what percentage of all our toilets are water efficient?

It’s not a high percentage. It’s about 15 to 20 percent. That’s primarily because of people not having the wherewithal to change out the toilets that were put in place before 1992. In 1992 there was a change in the flush law for new toilets, which reduced the flush volume to 1.6 gallons. Before, it was 3.5, 5 or 7 gallons a flush. So as you can imagine there’s such a huge infrastructure in the marketplace of embedded products. You have some homes today that have four or five bathrooms in the home, and some homeowners may not change every toilet.
