Sewer backed up. The digging has begun.
Black clean out pipes. Behind the ladder is part of the maze of pipes that all my crap went through.
You can see the black cleanout drain here. Somehow this was connected to those pipes on the left side of the photo (behind the ladder) and then to an old clay pipe which is on the right side of the photo.
This is the old clay pipe that the sewer has been draining into. We are not sure if this is connected to anything.
