    What is the max length of a 2" shower drain before it needs to be vented ? The 2" drain pipe is directly attached to the main 4" stack that is vented vertically with a 3" dry vent. Is 4 feet of un-vented 2" drain pipe allowed ?

      Depends on the code in your area! Talk to your plumbing inspector.

      Yes, I'm still a master plumber. You need to date when something happens. The physical laws governing how plumbing systems function are not changing anytime soon, so my advice above is timeless.
