I have an inspector who wants me to prove that calculating run or through tees is appropriate for 13 Residential systems.
I showed them that run tees are in 13D, he thinks they should be calc'd in 13? How do I prove something is not in a code?
Any help would be appreciated.

Residential single-family dwelling is getting an NFPA 13D sprinkler system with a pump and water storage tank.
Is the test line required to be routed to the exterior, or can it be run back to the water storage tank? I've seen it both ways but don't see an applicable code section.
