Commercial Prerinse Spray Valves

A commercial pre-rinse spray valve is designed to remove food waste from dishes prior to dishwashing, and is often used in commercial and institutional kitchens, such as large restaurants and food service operations. Prior to loading the dishwasher, plates and dishes and utensils are manually sprayed (pre-rinsed) to remove loose or sticky food. Dishwashing typically consumes two-thirds of all large restaurant and food service operation water use. The water used in the pre-rinsing operation is often twice the volume of water used by the dishwashing equipment. 

The Energy Policy Act of 2005 established standards for water flow rate and prescribed test procedures for commercial pre-rinse spray valves. The Department of Energy (DOE) codified the energy conservation requirements under subpart O of Title 10 of the Code of Federal Regulations, Part 431 (10 CFR Part 431)

DOE estimates that the current water flow rate standard will save approximately 1.4 quads of energy and result in approximately $20.8 billion in energy bill savings for commercial pre-rinse spray valve equipment shipped from 2007 to 2031. Further, the standard will avoid about 75 million metric tons of carbon dioxide emissions, equivalent to the annual greenhouse gas emissions of about 14.7 million automobiles

Recent Updates

DOE has published a Federal Register notice of withdrawal and republication of the notice of data availability (NODA) regarding commercial prerinse spray valves. 80 FR 72608 (November 20, 2015). DOE has withdrawn and republished the NODA published in the Federal Register on November 12, 2015 (80 FR 69888) due to errors in that published document. DOE has republished this document in its entirety. DOE will accept comments submitted no later than December 4, 2015. This clarification has no impact on the results.  For more information please see the rulemaking webpage.

Standards for Commercial Prerinse Spray Valves

The following content summarizes the energy conservation standards for commercial prerinse spray valves. The text is not an official reproduction of the Code of Federal Regulations and should not be used for legal research or citation.

Current Standard

Commercial prerinse spray valves manufactured and distributed in commerce, as defined by 42 U.S.C. 6291-(16), on or after January 1, 2006, must meet the energy conservation standards specified in the Code of Federal Regulations, 10 CFR Part 431.266, and shall have a flow rate of not more than 1.6 gallons per minute.

  • Final Rule: Standards, Federal Register, 70 FR 60407 (October 18, 2005)
  • Docket ID EERE-2005-0002 contains notices, public comments, public meeting transcripts, and supporting documents

Test Procedure for Commercial Prerinse Spray Valves

Current Test Procedure

To determine compliance with energy conservation standards for commercial pre-rinse spray valves, under subpart O of the Code of Federal Regulations, a manufacturer is required to follow the test method prescribed under 10 CFR 431.264 for commercial pre-rinse spray valves as of January 1, 2006.

For further guidance or to submit questions related to the implementation of this test procedure, visit the Guidance and Frequently Asked Questions page.

Waivers, Exceptions, and Exemptions


Test procedure waivers have not been issued for commercial pre-rinse spray valves. For information about obtaining test procedure waivers, see  subpart V of 10 CFR Part 431.


DOE's Office of Hearings and Appeals has not authorized exception relief for commercial pre-rinse spray valves.

For information about obtaining exception relief, see 10 CFR Part 1003.

State Exemptions to Federal Pre-emption

DOE has not exempted any state from this energy conservation standard. States may petition DOE to exempt a state regulation from preemption by the Federal energy conservation standard. States may also petition DOE to withdraw such exemptions. For details, see subpart W of 10 CFR Part 431.

Statutory Authority

The current energy conservation standards for prerinse spray valves are mandated by Part A, the ‘‘Energy Conservation Program for Consumer Products Other Than Automobiles’’ of Title III of the Energy Policy and Conservation Act (EPCA), as amended. (42 U.S.C. 6291–6309) Pre-rinse spray valves are treated as a covered product under Part A. (42 U.S.C. 6295(dd))

Historical Information

The Energy Policy Act of 2005 (EPACT 2005) amended EPCA and directed DOE to promulgate new or amended energy conservation standards for various consumer products and commercial and industrial equipment. In addition, Congress prescribed in EPACT 2005 efficiency standards, test procedures, and related definitions for certain consumer products and commercial and industrial equipment, including commercial pre-rinse spray valves. DOE incorporated the Congressionally mandated water flow requirement for commercial pre-rinse spray valves into subpart O of 10 CFR Part 431 on October 18, 2005.
