Not in 13D – Support is not sent back to 13 so currently it appears to be a loophole. However, according to Spears the bigger issue would be product compatibility which arguably is even more important than the slight weigh of duct.

Politicians sidestep the original question, fail to answer, distract into another direction. Regarding NFPA 13D, it's silent on sprinkler piping or hangers shall not be used to support non-system components. I'm looking for a confirmation that is a true statement.

The pipe is supported by holes through the wood joists. I thought NFPA 13D would prohibit sprinkler pipe from supporting other trades, but I don't seem to find it. It's spelled out in NFPA 13, 9.1.1.8 and 13R, 6.13. Did I miss it in NFPA 13D?
