Right. I was handicapped by not wanting to fill in the trench unless I knew there were no leaks in the new PVC I glued. I didn't want to fill in the trenches only to have to dig them out again to fix the leaks. But leaving the trenches unfilled just to ensure that the connections weren't leaking would allow the new PVC pipe to flex enough that the existing O-PVC could slide and then start leaking 20 feet away. I was at my wits end. Fortunately the plumber came up with the smart idea of using 90° elbows and stout rods driven into the ground at each elbow to keep the existing O-PVC from sliding.
