I have to replace a 45 degree bend in my concrete sewer line that was damaged by roots. Can I do this with ABS? I know I can make the connection to one (non flared end) with a rubber adapter boot, but how do I make the connection to the other side on the which is flared? Also I want to put in a clean out at ground level. What's the best way to do this with parts available at a home center... (It's the weekend, plumping supply houses are closed).
