What to Know About Toilet Flushing & Water Usage
Toilet Efficiency Keeps Improving. Standard toilets now use approximately 1.6 gallons of water every time the toilet flushes. However, some ultra-high-efficiency toilets use as little as 0.8 gallons every time the toilet is flushed. That''s not very much water when you consider that toilets of the 1950s used as much as 7 gallons!
