Pre-Rinse Spray Valves Specification Version 1.0

In 2009, the EPA’s WaterSense and ENERGY STAR Programs launched an effort to collaborate with ASME and ASTM in developing a performance and efficiency criteria that would inform a joint EPA specification for Pre-Rinse Spray Valves (PRSVs).  In 2012, EPA decided not to pursue joint requirements and instead, promote the EPA’s WaterSense PRSV specification once finalized.  For more information on the EPA WaterSense PRSV program, visit http://www.epa.gov/watersense.

Notice of Intent - July 10, 2009

EPA has issued a Notice of Intent to develop a specification for high-efficiency pre-rinse spray valves. This NOI outlines EPA's approach to developing the draft specification, the efficiency and performance criteria EPA is working to define, and the technical issues that still need to be resolved related to these products.
