Wayne, I have recently been chasing all types of PVC breaks in an irrigation system.

Steve's suggestion is the way to go. Minimum schedule 40 repairs, the thin wall will become brittle and crack along the pipe. To prevent that from happening, use either a sawzal or a multitool. PVC cutters could cause the pipe to split longitudinally.

One thing and it is important, trench bedding. The original install with pipes crossing as in your case was probably caused by the upper pipe pushing down on the lower. Pipes should NEVER rest on one another, ever. That said, bed the repair with sand. Sand will fill any shadows under the lower pipe and mitigate any flexing.

Good luck with the repair.
