With concern for the environment rising, many homeowners are looking for simple but practical ways they can lessen their ecological footprint. Reducing water consumption is a great first step. Since toilets are responsible for about 25% to 30% of indoor water use, a low-flow toilet would seem a smart way to painlessly reduce overall usage.
But how much water—and money—does a low-flow toilet really save?
Save Big When You Ditch An Old Toilet
How much water you’ll save by upgrading your toilet depends greatly on the flush volume of the toilet you currently have. Since 1992, the U.S. federal standard for toilets has been 1.6 gallons per flush. By comparison, toilets made between 1980 and 1991 used as much as 3.5 gallons per flush and older models used up to 7 gallons per flush.
