The 2" PVC elbow shown in these pictures is leaking at the joint where it connects with a PVC pipe coming through the foundation stem wall at the right.
What's the best procedure for replacing this elbow? Is it possible to remove the elbow without damaging the wall pipe that it connects to?
I'm willing to replace all of the pipe and fittings above and to the left of the elbow and that lead to the sump pump. However, I hope to avoid replacing the pipe that comes through the stem wall, since that would involve excavating outside the house.
