Hope that elbow ain't anywhere near anything you really like in the yard.

At least that should fix those kinds of problems for a long time.
In the 35 years we lived at our old house replaced the sewer lines twice.
When I was 6. and again when I was 18.
First time was because it was that orange bird tile carp.
Everyone in the neighborhood had to redo theirs at about the same time.
Second was because Dad planted a cherry tree right on top of the lines.
Don't remember what they used the second time, but went with pvc the 3rd.
Seems to have done the trick, has been good since, over 30 years.
When I helped my brother do his, he put in cast iron.

If the clean out is any indication this house has pvc.
Haven't had any issues for 20 years...knock on wood.
