EPA sunset the WaterSense Specification for Commercial Pre-Rinse Spray Valves in January 2019 and no longer labels these products. As of January 28, 2019, all commercial pre-rinse spray valves sold in the United States will be required to meet the revised federal energy standard issued by U.S. Department of Energy (DOE). The new DOE regulation classifies pre-rinse spray valves into three product categories, differentiated by spray force, and requires products to be performance tested according to ASTM F2324, the standard that WaterSense and its partners worked to modify and improve during specification development process. The changes to the regulation essentially remove the need for the WaterSense label to differentiate these products in the marketplace, as products meeting the federal standard will meet (or exceed) the previous WaterSense labeling criteria for water efficiency.
