Hi, All! Still after reading many threads,,back to page 7, and having never installed double wall, my question is?
Does the inner pipe lap one way while the outer pipe laps the opposite? Or, in another form of question,,,on the same end of any given double wall Class A pipe, is the inner pipe "Male", while the outer pipe is "Female"?
