So I bought some pipe to put a vertical rise on, I bought 4", ( thought mine was 4") evidentally my pipe is a 3" ( probably 85% of my burning problems right)
anyway, can I attach the 4" to the 3" if I tape and or clam the joint or is that not recommended. Also should I put a clean out T on it or can I just 90 it up?
