Surprisingly, toilets use a lot of water.
Older models can use up to seven gallons of water per flush according to Conserve h2o.
However newer toilets can use as little as 1.6 gallons of water per flush. Newer models of toilets have begun to be more efficient and use less water after it was found how much water toilets actually use.
It was estimated that toilets use up to 24% of Americans water use.
This number is so high not only because toilets use a lot of water to flush, but also because of toilet leaks. When left unchecked, toilet leaks can lead to a lot of water waste.
