That’s funny. I believe that statement has been in the standard since before flex drops were even available.

We were told that the only instance where isolated drops that numbered greater than 20 would not require hydrostatic testing at 200 psi was if they were existing flex drops that were relocated within the original radius of the flex drop and they weren't removed from the existing system. Their position was that, despite the commentary in the handbook, and the engineers opinions from NFPA's interpretations, the intent of this code is only referring to relocated flex drops. B.J.

NFPA 13 2013ed 25.2.1.6 says “modifications that cannot be isolated, such as relocated drops, shall not require testing in excess of system working pressure” The mechanical t’s could not be isolated, but since they were added heads and not “…such as relocated drops…” the AHJ required us to test the entire existing floor at 200psi. Has anyone seen this before?
