Terry and everyone...
Another thread here https://terrylove.com/forums/index.php?threads/how-do-i-join-2-75-cast-pipe-to-3-inch-pvc-tee.53671/ you suggest a copper to CI mission coupling. The OP of the thread appears to be speaking of an above-ground connection.
My question is exact to the other poster's question. The project I have is in a house built in the 60's in Southern California. The buried drain line in a "3in. cast iron pipe". I have to relocate the toilet drain. A section about 6 feet is damaged anyhow and is being replaced with 3 in. ABS. In this case, as is the case with the referenced thread, the cast iron is approx. 2 3/4 in. I.D. and 3 1/4 in. O.D. Obviously current 3 in. ABS in not the same sizes, inside or outside.
Current Mission product offerings do not have a compatible coupling. Our major plumbing supply here is White Cap. I don't know if you have ever heard of them or not, but would I be asking for the same Copper to CI Mission Coupling you reference in the other thread?
BTW, this section pipe is mid-stream, between the furthest clean out and the rest of the house. It's all in one straight line with only single fixtures branching off. So, this section goes from the 60's 3in. CI to 3in. ABS and back to 3in. 60's CI.
