Is there a way to get a message to the writers of the Code Check books?
The gas sizing table in new edition of the plumbing book only goes up to 1 1/4" pipe and 150 ft. The earlier one went to 2" and 250 ft. Do the codes differ now for larger pipe and longer runs, or was that done to save space? The replacement run to my BIL's pool heater may have to be over 150 ft to avoid obstacles that have been built and grown since the original was put in.
