I have had a busy time at work and I am now getting back to my bathroom renovation project
The picture below shows what I am trying to do
I would like to avoid digging out the pipe and cutting out the concrete to the right of the picture
Ideally I would like to join the existing and the new drain pipe near the right edge of the opening you see in the picture. What options do I have ? I do not like the flex connectors I do not think it is a good idea to leave then under ground. Just to be clear am installing a shower base there and relocating the sink drain
Here is the overall plan for the plumbing for this section of my project, The angles we are talking about are not exactly rendered in the diagram below

I would use a 22-1/2 degree elbow and flex the pipe if they won’t do it because of the short space a fernco or no hub in the middle will give a couple degrees they are not designed to be flexed but a slight couple of degrees will work if you can’t make a small bend with heat a hair dryer may be enough with abs to get the extra bend if you don’t want to use a fernco. I would never use the corrugated flex pipe and especially not under a slab. But the elbow and a bit of bend in the pipe should do it.
