How do HETs compare to older toilets?
Some toilets made before 1980 used as much as 5 to 7 gallons of water per flush (gpf). If you swap one of those antiques for a high-efficiency toilet (HET), you could save as much as 5.7 gallons per flush. One person using one HET five times a day would save almost 30 gallons of water. A family of four, 120 gallons a day. In a year, that family could save almost 44,000 gallons of water by switching from a 7 gpf toilet to a 1.28 gpf high-efficiency model.
