I needed to replace a damaged section of 4" PVC (and add a proper drain for our washing machine). It seemed to be a no-brainer, the existing PVC attached to cast-iron near the floor. But when I removed the old connectors, I discovered that the "stub" of cast iron was corroded and cracked, and now leaks. This "stub" is only 5" long and leads into a cast-iron wye that comes up through the concrete floor. Obviously, the cracked "stub" needs to come out, but then how do I connect into the wye? And what would be the best way to remove this "stub" without damaging the wye? thanks
