Most toilets marketed before 1977 can expend an average of 6 gallons of water with each flush. That’s as much water as NASA astronauts are allowed to use for an entire day.
In this video, plumbing expert Dave Charvet describes the discrepancies between water-efficient and inefficient toilets. Toilets made before 1977 use between 5-7 gallons of water with each flush, whereas toilets made after 1992 use 1.6 gallons per flush. Though 1.6 gallons is the current legal maximum, the newest water-efficient toilets expend only 1.28 gallons or less per flush. Look for an EPA Water Sense sticker when toilet shopping to guarantee you are buying the most efficient model possible.
