Adding a PVC sewer drain clean out to old terracotta pipe.

I have an old house with terracotta drain pipe. There's a cracked pipe section that I need to replace so I figured I would put a cleanout pipe there and kill 2 birds with one stone. This cracked pipe is on the side near where 2 pipes connect on the house side which would be the female side of the pipe.

I was thinking I would cut that cracked section where I need to and remove the female connection piece and just use the original male end of the next pipe to connect my cleanout to. Is that doable? Or should I just make 2 fresh cuts and cut the connected section out altogether?

 

You can make the cuts wherever you want. Just get the Fernco (rubber boot) or no hub couplings needed to fit the pipe.

I would remove one complete section of terra cotta and replace with PVC. That way you remove two terra cotta to terra cotta joints.
