Pre-Rinse Spray Valves

The EPA WaterSense and ENERGY STAR Programs have agreed to collaborate with ASME/CSA and ASTM to develop performance and efficiency criteria that will inform an EPA specification for Pre-Rinse Spray Valves (PRSVs).

The goal is to involve a broad set of interested stakeholders through a joint committee process to develop test procedures and specifications that deliver water and energy efficiency while ensuring product performance and quality. This effort was launched on October 6, 2009 at a meeting preceding the WaterSmart Innovations Conference in Las Vegas, NV.

Consistent with procedures in both programs, EPA is periodically updating stakeholders on the progress of work carried out to develop the specification and seeking input as needed. EPA expects this joint effort to result in a specification that meets the program principles of both ENERGY STAR and WaterSense.

EPA encourages all interested ENERGY STAR and WaterSense stakeholders to participate in the ASME/CSA task force process, which is open to all. For assistance in joining the ASME/CSA task force, or if you have any questions about the specification development process, please email watersense@epa.gov.

Pre-Rinse Spray Valves Field Study—January-June 2010

To ensure the efficiency and performance of high-efficiency PRSVs before they can earn a label, EPA conducted a field study to assess PRSV water use, energy use, and performance. Information regarding the scope and results of the PRSV field study are found below:

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.
