WaterSense High Efficiency Toilets*

How Much Water and Money Do HETs Save?

High-efficiency toilets save you money by reducing your water and wastewater costs. Over the course of a lifetime, an average person flushes the toilet nearly 140,000 times. If you install a WaterSense HET, you can save 4,000 gallons per year and your children can each save about a third of a million gallons during their lifetime. If a family of four replaces one 3.5 gpf toilet made between 1980 and 1994 with a WaterSense toilet, they can save $2,000 over the toilet's lifetime. If the toilet being replaced was made before 1980, it uses 5 gallons per flush, so the savings will be much greater.

The WaterSense label can be applied to HETs certified by an independent testing laboratory to meet strict criteria for both performance and efficiency. HETs must complete the third-party certification process to earn the right to bear the WaterSense label.

Do High-Efficiency Toilets Work?

Everyone is concerned about the performance of low-flow toilets. Do they clear the bowl and leave it clean? Do they stop up frequently? Unlike the first 1.6-gallon / flush toilets, WaterSense HETs combine high efficiency and performance. Advances in toilet design permit WaterSense HETs to save water without losing flushing power. Many HETs perform better than standard toilets, a testament to using computers to design them rather than the trial-and-error guesswork of earlier designs.

Benefits of High-efficiency Toilets

Water conservation: High-efficiency toilets (HETs) use significantly less water per flush than traditional toilets, saving significant water over time. This is especially important in areas with water scarcity or drought-prone regions.

Cost savings: Because HETs use less water, they can help reduce your water bills over time. While the initial cost of purchasing a HET may be higher than that of a traditional toilet, the long-term cost savings can be substantial.

Environmental benefits: By reducing water usage, HETs also help reduce the energy needed to treat and transport water, which can help reduce greenhouse gas emissions and other environmental impacts associated with water use.

Improved performance: Modern HETs are designed to provide reliable and consistent flushing performance, so you don't have to sacrifice performance for water savings. Many HETs use advanced flushing technologies, such as pressure-assisted or dual-flush systems, to provide powerful and effective flushing with less water.
