I included this reference in my response. From 4 different editions of 13. As well as a half dozen informal interpretations from AFSA and explanatory comments from the handbook.

I don't believe we're all just putting 200 psi on other people's pipe. Anything saved from AFSA, NFSA or NFPA would be great.

So we're playing the game of escalation and code interpretation. Does anyone have a code interpretation from AFSA, NFSA or NFPA on this? Her stance is that the code says "such as relocated drops" and I may have added a few drops. I am sure we have all come across this right?
