Our house is on a concrete slab. We are planning on installing a second-floor full bathroom, and hoping to connect the new bathroom 3'' PVC waste pipe to the below-grade drainage system at this point:
I think that this (oakum/lead filled) fitting connects the visible 2 inch pipe to a 3 inch, cast iron pipe buried below the concrete: on the one hand there is '3-2' molded on the exterior, and on the other hand, a few feet downstream, there is a WC that must feed into that very same submerged cast iron pipe.
But I could not find this fitting/hub on the web to be absolutely sure.
Does a) anyone recognize the fitting to identify it? Well enough to provide a specific reference? [I have no guess as to the meaning of the XH molded in high relief on the fitting.] And b) do you agree that it is fitted to a submerged 3 inch pipe?
Assuming some positive answers to the preceding, my follow-up question is: will I have to remove the hub/fitting to connect the new 3'' PVC? Namely, does this fitting constitute the equivalent of a 3 inch diameter 'long radius 90 degree elbow' or (better) a 45 degree elbow?
I am assuming that the fitting will have to go, and I will have to break up enough of the concrete to join to the hoped-for, 3-inch cast iron pipe.
To be clear: we are replacing/removing the 2'' DWV pipe in the image above.
FWIW – I am drawing up plans to submit to the town, and would like them to correspond somewhat to reality.
Thanks in advance!
- Edit: As Ecnerwal points out in the comments, the 'XH' surely means 'extra heavy.'

If it doesn't connect to a 90 degree elbow hooked to a wye laying on its side, it was done wrong in the first place. That's the only situation you should have to bust up concrete.
