Could be that is what happened. If NFPA goes back and puts all the RoP's and RoC's on line I will research this further. Or it can wait until the next time I am in the Commonwealth of Massachusetts and can spend a few hours at the NFPA library. I am not confident that I will find the answer. Sometimes these things just morph -- even non-technical editors do clean up revisions of text without realizing the subtleties involved.

Looking back into earlier editions of 13 (like the 50's), there was a prohibition against installing used sprinklers. Now the text says only new sprinklers shall be installed. I think there is a difference in meaning.

Also, if you remove the sprig/drop/arm over and replace it, but do not touch the sprinkler, would that be legal? I wonder what the "bad experiences" have been had with reconditioned sprinklers. What kind of reconditioning did they use? At 01:05 PM 2/6/2009, you wrote: >I know what the code says but it seems wasteful to use these heads >for 24 hours and then throw them away.
