I repaired a collapsed section of 8-inch clay sewer pipe today. Used a RIDGID SeeSnake camera to locate the damage. Excavated the area with a Bobcat mini-excavator. Removed the damaged pipe and replaced it with SDR 35 PVC pipe. Applied PVC primer and cement to joints. Backfilled trench with gravel and compacted soil. Tested flow with hydrostatic pressure test.
