The average house in the United States is 37 years old, and half of U.S. homes are more than 50 years old. That means most toilets were installed before 1992, when the Environmental Protection Agency mandated the use of ultra-low-flush toilets. Those old toilets use 18.8 gallons per flush, 17.2 gallons more than new toilets. Want to lower your water bills and waste less clean water? Upgrade your toilet!
