On December 19th, the U.S. Environmental Protection Agency (http://www.epa.gov/ EPA) released the “Draft WaterSense Specification for Flushometer-Valve Water Closets,” which was written to ensure that flushometer-valve toilets that earn the WaterSense label in the future are water-efficient while still performing at high levels.

The EPA proposes a maximum flush volume of 1.28 gpf for both single- and dual-flush flushometer-valve toilets. In the future, replacing one old, inefficient flushometer-valve toilet with a WaterSense-labeled model may save more than 5,400 gal. per year, according to the EPA.

Interested parties are welcome to comment on the proposed requirements until Feb. 20. Thoughts and suggestions should be emailed to watersense-products@erg.com. If you have questions about the proposal please call the WaterSense Helpline at 866/987-7367 or email watersense@epa.gov.
