In an average home, toilets are the main source of water usage each day.
You will likely flush nearly 140,000 times over the course of your lifetime, according to the EPA. With each flush of a toilet, you use roughly 3-5 gallons of water, with some older models using up to 7 gallons per flush. To conserve water and save money, some homeowners opt for a small tank toilet or dual-flushing toilet.
By opting for a greener toilet, homeowners can potentially save thousands of gallons of water each year and knock as much as $90 off of their annual water bill, according to HouseLogic. High-efficiency toilets aren’t cheap–they can cost anywhere from $200 and up–but over time, they can pay for themselves.
