What are Ultra-Low Flow or High-Efficiency (HET) Toilets?
Under federal law, toilets must not exceed 1.6 gallons per flush. High-efficiency toilets go beyond the standard and use less than 1.3 gpf. The EPA’s WaterSense label is used on toilets that are certified by independent laboratory testing to meet rigorous criteria for both performance and efficiency. Only toilets that complete the third-party certification process can earn the WaterSense label. Visit the web page listing the models that meet the WaterSense criteria to find the best high-efficiency toilets. • I heard the new low flow toilets don’t work well.

Since then, manufacturers have invested in research and development to design low volume toilets that work as well as or better than the ones they replace. Customer satisfaction surveys confirm that owners of low-flow toilets rate them highly 90 percent of the time. If you would like additional information regarding toilet performance visit the Cal
