I have a copper stack to roof and this galvanized pipe to copper is a vent from the downstairs kitchen sink. What I'd like to do is replace the elbow with a tee to vent a new bath sink (1-1/2") but I don't see how I can remove the elbow. My only idea is to cut the copper and cut the galvanized and use shielded couplings to connect a PVC Tee. Any better ideas?
