  2. Toilets are by far the main source of water use in the home, accounting for approximately 30 percent of residential indoor water consumption. Toilets are also responsible for most of the water wasted in American homes due to leaks and/or inefficiency. Replacing toilets with WaterSense labeled high-efficiency models (HETs) could save approximately two billion gallons per day across the country.

    WaterSense is a program sponsored by the U.S. Environmental Protection Agency (EPA) that helps consumers identify high-performance, water-efficient toilets that can reduce water use in the home and help preserve the nation's water resources.

    High-efficiency toilets go beyond the federal standard of 1.6 gallons per flush (gpf) by using less than 1.3 gpf. By replacing an older model toilet with an HET, a family of four could reduce its water use from the toilet alone by 60 percent and save more than $90 annually on their water bill, and $2,000 over the lifetime of the toilet. Savings could be as much as two to three times that amount if the model being replaced is a leaky toilet or a pre-1980 model that uses 5.0 gpf or more.

    With these savings, a new WaterSense labeled HET can pay for itself in only a few years. Additionally, the Denver Water Department offers a $125.00 rebate for replacing old toilets with HETs.

    But What About Performance? Unlike first generation "low-flow" toilets, WaterSense labeled HETs combine high efficiency with high performance. Design advances enable WaterSense labeled HETs to save water with no trade-off in flushing power. In fact, many perform better than standard toilets in consumer testing.

    So whether you're remodeling a bathroom, building a new home, or simply replacing an old, leaky toilet, an HET is a high-performing, water-efficient option worth considering.
