HIGH EFFICIENCY TOILETS
Under U.S. Federal law, new toilets must not use more than 1.6 gallons per flush (gpf). High-efficiency toilets (HETs) go beyond the standard and use 1.28 gpf, a 20% savings (6 liters v. 4.8 liters). A few of the new toilets use even less, only 1.1 gallons (4 liters). The WaterSense label can be applied to HETs that are 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.
