Above states "If your project is registered after the 11/1/2011 addenda release then the pre-rinse spray valve flow rate must be 1.6 gpm or less in order to comply with the prerequisite. If your project has a pre-rinse spray valve that has a higher flow rate than 1.6 gpm, then the project is not in compliance and the pre-rinse spray valve would need to be revised in order to be eligible for LEED certification."
Our project was registered before 11/1/2011. Therefore it does not have to comply with this addenda. However, on the LEED online form requires that we do. Any suggestions if we have to document them or not? Or where/how we express our reasoning for not including them?

James, the version of the form you are using may have been updated after that date, and therefore be requiring that documentation.I would include in the narrative section a note about your registration date as reason for your documentation choice.

Hi James,
Not sure if you’ve already proceeded with your formal project review since you posted this inquiry (and if so, would appreciate your feedback here on the outcome), but to help clarify, the 11/1/2011 Addenda indicates that for projects with commercial pre‐rinse spray valves, there is no longer a baseline performance standard from which to claim savings; rather, the prerequisite requires only that the flow rate comply with the ASME A112.18.1 standard of 1.6 gpm or less.
Since your project was registered before 11/1/2011, the pre-rinse spray valve flow rate may exceed 1.6 gpm provided that the pre-rinse spray valves are included in the Form flow fixture table calculations and you are able to demonstrate that – in aggregate – the project has reduced water by at least 20% as required by the prerequisite. Alternatively, the you can confirm that the pre-rinse spray valves have been replaced to meet the 1.6 gpm max flow rate.
