Try these various cameras. Not all work at the same time.

Most of the action is on this cam right now.
My analysis is that there is a tear on the right side that might be the failed diamond saw cut. It appears to be just above or perhaps at the point where the flange was welded to the pipe. The seal will be effected below that on the flange body
The current effort seems to be to make vertical cuts that can be folded inward slightly to allow the cap to fit over the pipe stubout and in good close contact with the slightly tapered flange. the slight taper of the flange body will permit a tight and regular seal.
Thank you
