Bob, The committee wants to see relative elevation changes. This helps with lengths of pipe and calcs too. We use the word relative because it doesn't need to be Above Sea Level. (But I think you already know this!!)
Cecil It should be recognized that the above is my opinion as a member of the NFPA, and has not been processed as a formal interpretation in accordance with the NFPA Regulations Governing Committee Projects and should therefore not be considered, nor relied upon, as the official position of the the NFPA, nor any of their technical committees.
