The maximum length of a clothes dryer exhaust duct shall not exceed 25 feet from the dryer location to the wall or roof termination. The maximum length of the duct shall be reduced 2.5 feet for each 45-degree bend and 5 feet for each 90-degree bend. The maximum length of the exhaust duct does not include the transition duct.


The correct answer is C.

I had to note this on an inspection the other day as in need of repair on a home that was framed up, no sheetrock.


If I hadn’t known what the max length of the dryer vent was supposed to be, how am I to know to write up as in need of repair?


Thanks for dong a good job of posting questions like this that keeps everyone refreshed on what we are supposed to already know.

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.
