Toilets

Water–Efficient Toilets

Toilets are by far the main source of water use in the home, accounting for nearly 30 percent of an average home's indoor water consumption. Older, inefficient toilets that use as much as 6 gallons per flush also happen to be a major source of wasted water in many homes.

Water–efficient toilets, such as low–flow toilets, are a great way to reduce household water use.

Flush Facts

Recent advancements have allowed toilets to use 1.28 gallons per flush or less while still providing equal or superior performance. This is 20 percent less water than the current federal standard of 1.6 gallons per flush. The WaterSense label is used on toilets that are independently certified to meet rigorous criteria for both performance and efficiency. Only water–saving toilets that complete the certification process can earn the WaterSense label.

WaterSense Savings

By replacing old, inefficient toilets with WaterSense labeled models, the average family can reduce water used for toilets by 20 to 60 percent—that's nearly 13,000 gallons of water savings for your home every year! They could also save more than $110 per year in water costs, and $2,200 over the lifetime of the toilets.

Nationally, if all old, inefficient toilets in the United States were replaced with WaterSense labeled models, we could save 520 billion gallons of water per year, or the amount of water that flows over Niagara Falls in about 12 days.

Look for the WaterSense Label!

Whether remodeling a bathroom, starting construction of a new home, or simply replacing an old, leaky toilet that is wasting money and water, installing a WaterSense labeled toilet is a high-performance, water-efficient option worth considering. WaterSense labeled toilets are available at a wide variety of price points and a broad range of styles and in many areas, utilities offer rebates and vouchers that can lower the price of a WaterSense labeled toilet.

A WaterSense Labeled Toilet Factsheet is also available in PDF (1 pg, 296K, About PDF).
