Flushometer-valve toilets are typically found in commercial, institutional, or industrial restrooms, in such places as airports, theaters, stadiums, schools, and office buildings. These types of toilets have two main components—the toilet bowl and the flushometer valve.
To help commercial facilities become more water-efficient, in August 2013 WaterSense issued a Notice of Intent (12 pg, 100K, About PDF) (NOI) to develop a specification for flushometer-valve toilets. WaterSense estimates that there are approximately 26 million flushometer–valve toilets currently installed in the U.S. Many of the older flushometer–valve toilets currently installed use 3.5 gallons per flush (gpf) or more—far more water than the federal standard of 1.6 gpf. With many of these models reaching the end of their useful life, replacing them with more efficient models could result in significant water savings. If commercial facilities nationwide replaced all of their older, inefficient and standard flushometer-valve toilets with high-efficiency versions, it would save an estimated 56 billion gallons of water per year.
Due to increased demands for improved toilet performance and a growing emphasis on water efficiency, manufacturers are producing high-efficiency flushometer-valve toilets. These toilets are designed to use no more than 1.28 gpf—a 20 percent water savings over standard 1.6 gpf toilets. In the future, EPA's specification will ensure that all flushometer-valve toilets that earn the WaterSense label will perform well while still saving water.
On September 12, 2013 EPA held a public meeting to address questions regarding the NOI and gather input from stakeholders for specification development. For more information, please review the following documents:

WaterSense is encouraging all interested parties to continue to provide input on any of the issues presented in the NOI to label flushometer–valve toilets. Please send any comments or suggestions to email@example.com. WaterSense is in the process of reviewing comments and developing a plan forward for the draft specification.
