Had to change this question around due to more details. When I first started digging around the sewer line yesterday, I presumed this based on what I saw in the ground:
An original cast iron pipe that is visible (the far left pipe next to the a/c) in the crawlspace. Then I found what I thought were two extra pipes to the right side of it. One had a section a couple of feet long. Looks like maybe clay pipe with the larger end facing the sewer pipe side. Just laying there in the ground with no connection on either end.
A "third" pipe ended up being small pieces of either the second pipe or perhaps what was left over from a third pipe that is no longer there. Hard to say which. Got all of those out, and I'm left with this:
Main sewer pipe joins with the active sewer pipe coming out of the crawlspace, but there is some kind of connection branching off from the main sewer pipe that looks like it might have gone to one of the old pipes that aren't there any longer. I've never seen anything like that before.
