    Question Proper way to tie into mid run of a under slab main.....?

    I'm adding a lav and a shower midway through the run of my main under slab. Routing and venting are all addressed and to code. My question is what is the proper way to cut into the main and add in my wye fittings when I do not have any end movement to get the pieces all back together. I do not have enough movement sideways in the main pipe to move it aside to squeeze in the last fitting. I guess I can cut the pipe a little shorter then add in a rubber coupling at the end????

    Plumbers would have cut the fittings in FIRST, and then worked from there to the new location.

    That's exactly what I'm doing. I just need to know the correct way to to fit the stack back together whne installing the last fitting in the main. I would think a rubber coupling might be needed to join the main back together in order to get the last fitting installed. ??? Thanks
