Pre-rinse spray valves – May 2016

Technical bulletin on developing the standard

Webinar - June 2016

On April 30, 2016, Natural Resources Canada's Office of Energy Efficiency issued a Notice of Intent to introduce and align Canada’s EnergyEfficiency Regulations (the Regulations) for pre-rinse spray valves (PRSV) with standards in the United States. This technical bulletin has been released to initiate the consultation process and to collect stakeholder views on the requirements being considered for PRSV.

Input received during this stage of the process will inform the development of the Amendment 14 proposal.  In addition, the department will undertake a cost-benefit analysis using the best-available Canadian market data to assess the economic and environmental impacts of aligning these standards and to ensure Canadian consumers and businesses benefit from its implementation.

The Government of Canada intends to pre-publish a regulatory proposal in the Canada Gazette, Part I within approximately one year of this bulletin.


PRSV are not regulated products in Canada.  In October 2005, the United States Department of Energy (U.S. DOE) issued a final rule, which established energy conservation standards for PRSV with effective date for compliance as of January 1, 2006 (Tier I).  Most recently, in January 2016, U.S. DOE issued a final rule, which established more stringent energy conservation standards for PRSV. The effective date for compliance with the amended standards for PRSV is January 28, 2019 (Tier II).

Natural Resources Canada (NRCan) is proposing to amend the Regulations and to adopt the U.S. levels and standards (Tier I and Tier II) pertaining to the energy performance of PRSV. If implemented, this proposal would ensure the Regulations for PRSV are aligned with those of the U.S. DOE.

Product description

 A pre-rinse spray valve is a handheld device designed and marketed for use with commercial dishwashing and ware-washing equipment that sprays hot water on dishes, flatware, and other food service items for the purpose of removing food residue before cleaning in commercial dishwasher.

Energy performance test procedure

NRCan is proposing that the following energy performance test procedure be referenced:

  • United States Code of Federal Regulations (CFR), Title 10, Part 431.264, Subpart O. The 10CFR uses the ASTM test method: ASTM Standard F2324-13 Standard Test Method for Prerinse Spray Valves.

This test procedure will be used without the use of a removable flow restrictor. This requirement is unique to Canada. This issue was raised by stakeholders during previous consultations.

The ASTM Standard F2324 test procedure is available from ASTM International website.

Energy performance standard

NRCan is considering maximum-allowable hot water flow rates for PRSV to align with Code of Federal Regulations (CFR) Title 10 Part 431.266(a), Subpart O for Tier I and Title 10, Part 431.266(b), Subpart O for Tier II:

Proposed MEPS for pre-rinse spray valves
Product class
(Spray force in ounce-force, ozf)
Maximum flow rate
Tier I
All classes 6.1 Liter per minute (L/min)
Tier II
Class 1 (≤5.0 ozf) 3.79 Liter per minute (L/min)
Class 2 (>5.0 ozf and ≤8.0 ozf) 4.54 Liter per minute (L/min)
Class 3 (>8.0 ozf) 4.85 Liter per minute (L/min)

Effective dates

These Regulations would come into force six months after the date of publication in the Canada Gazette, Part II.

NRCan is proposing that the Tier I standards for PRSV wouldapply to products manufactured on or after June 27, 2016.  The Tier II standards would apply to products manufactured as of January 28, 2019.

Labelling requirements

NRCan is not proposing labelling requirements for PRSV at this time.

Verification requirements

NRCan proposes that these products carry a third party verification mark indicating that the product meets the MEPS and that information to be reported has been verified.

The verification mark is the mark of a Standards Council of Canada accredited certification body that operates an energy efficiency certification program for the product.

Reporting requirements

Energy efficiency reports

The energy efficiency report required for PRSV will include the following product specific information:

  • name of product (i.e. pre-rinse spray valves)
  • brand name
  • model number
  • name of the manufacturer
  • name of the certification body whose verification mark will be affixed to the product
  • water flow-rate in L/min
  • spray force in ounce-force (ozf) (for products manufactured after January 28, 2019)

The Regulations apply to products imported or shipped inter-provincially for sale or lease in Canada. This report must be submitted, by the dealer, to NRCan before the product is imported into Canada or traded interprovincially for the first time.

Import reports

A dealer who imports these products into Canada must include the following information on the customs release document:

  • name of product
  • model number
  • brand name
  • address of the dealer importing the product
  • purpose for which the product is being imported (i.e. for sale or lease in Canada without modification; for sale or lease in Canada after modification to comply with energy efficiency standards; or for use as a component in a product being exported from Canada)

Comments invited

The purpose of this bulletin is to provide stakeholders with technical detail required to comment on the requirements under consideration for PRSV. 

NRCan is specifically interested in getting feedback on unique Canadian requirements:

  • use of flow restrictor during testing
  • limits of hot water in standard

Additional information on Canada’s Energy Efficiency Regulations including a current list of Standards Council of Canada accredited certification bodies can be found in the Department’s website.
