Yes An AHJ can ask for anything. We produce a letter outlining NFPA testing requirements to the GC and dissolve us of any libilaty due to testing existing system and we dont test until they agree and sign.

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? Matt
