I don’t understand the two “Are we code inspectors” questions.
No one is asking you to measure a duct that you suspect might be 25 and half feet long. But...if you saw one that was obviously 50 foot or longer, wouldn't you call it out as a component defect? If the answer is "Yes", then I have to ask why? Unless you have performed your own testing of the flow of lint at certain air-speeds within ductwork, you are relying on the work and results of others...or, in other words...code.
No...we are not strictly code inspectors, and I'm certainly not advocating quoting codes in the report, but much of what we do, know, and report on, is based on the expert recommendations contained in the codes. Otherwise, why call out a 14awg conductor on a 20 amp breaker?
Don't use the "I'm not a code inspector" as an excuse to not know (or learn) the stuff you should.
Greg...keep them coming. Good job as far as I'm concerned. This is supposed to be educational.
