HI
So as part of an ongoing renovation I'm planning I think I've figured out that to connect the waste of a new shower I either need to:
A/ Connect into an existing 40mm elbow at ground level that dives into a concrete floor. I don't have much experience with waste but I think this is solvent weld so would need to cut off the existing elbow just above ground and then somehow expose enough pipe beneath the concrete so I can get a new tee on.
OR
B/ Come through the back of an exciting stack with a 40mm boss at around ceiling level. I'd need to first remove the existing plywood boxing and then make good. Again no experience of doing this hence asking here. Also not sure whether I could "boss in" at the same height as the existing connection that you can see. Going lower shouldn't be an issue either.
So which is best/easiest ? Thanks a lot for reading and esp if you have a view?
