Hi all,
I'm confused about Table 906.1 and developed lengths in general. I've attached a diagram below of a venting system to try to understand.
The 2inch vent here is only 130ft long in total (80ft + 50ft), but then connects into this 4inch vent and travels another 100ft (40ft + 50ft + 10ft) before exiting through the roof. Does this 2" vent then satisfy the 150ft rule imposed by Table 906.1? Does this connection to the 4" pipe essentially "reset" the developed length?
I'd appreciate any input on this!
