Commercial Prerinse Spray Valves
The Department of Energy (DOE) has regulated the water consumption level of commercial prerinse spray valves since 2005. Typically, large restaurants and food service operations utilize commercial dishwashers. Prior to loading the dishwasher, plates and dishes 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 this pre-rinsing operation is often twice the volume of water used by the dishwashing equipment.
The current standard will save approximately 1.4 quads of energy and result in approximately $20.8 billion in energy bill savings for products shipped from 2007-2031. 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.

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.
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.

Current Test Procedure
To determine compliance with DOE standards, manufacturers must follow the test procedures specified at 10 CFR 431.264 for commercial prerinse 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.
Test procedure waivers have not been issued for commercial prerinse spray valves. For information about obtaining test procedure waivers, see 10 CFR section 431 subpart V.
DOE's Office of Hearings and Appeals has not authorized exception relief for commercial prerinse 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 10 CFR part 431, subpart W.
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))
The Energy Policy Act of 2005 (EPACT 2005) 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 new efficiency standards and related definitions for certain consumer products and commercial and industrial equipment, including commercial prerinse spray valves. DOE incorporated the Congressionally-mandated standard for spray valves into the CFR on October 18, 2005.
