I am tying into some old 4" CI drain pipe below grade. Should I cut out this section and use a No Hub or try to hammer a donut in? My worry with the no hub is the outside of the pipe is very rough. My worry with the donut is it will leak and this will be covered with concrete and a heated floor after. In the first pictures the main sewer line exits to the left, on the second one it exits to the top.
