Hi everybody. I'm deep into an interesting shower drain issue. Tasked with replacing a trap for a shower. Without getting long winded I'll put up some pictures as an illustration of what I'm working with. This building is all masonry and this shower trap cast into about 12' of cement. I need to get from a new shower drain and trap into the existing 3"wye. The problem I'm having is a 3" rubber bushing is too big and a 2" is too small. I'm missing something I guess. Any advice would be greatly appreciated.

    is that a hub you're looking at? could also try calling fernco or mission and see if they have different size doughnuts. different manufacturers and different weights of ci have different hub sizes.

    you'd need a runner to pour lead on a horizontal joint.

    is there a bomb shelter under that bathroom?

    I will look around for a different size. My first stop was F W Webb. Second stop was you guys.

    That's the living room below. 12' ceilings. Being renovated. There was a steam condensate leak at a tee in the ceiling/floor along with a roof leak running down a vent in the wall saturating the masonry. This destroyed the ceiling. We thought it was the trap. It was not but in order to find that out I had to dig.

    Not a plumber but I looked up the diameter of Ex heavy and service weight CI pipe and hubs and I saw nothing that was 3 1/4".

    Seems odd. My guess is it's actually 3" or was. I have a bushing marked 3" for SV and POG-3-SW but it's far too large to fit into the hub. Or seems to be. I recognize they are a very tight fit but this really seems excessive.

    Though I am unable to see if it's extra heavy or service my guess is extra heavy judging by how this building was put together.
