Grease-Blocked Drain Line Under a Concrete Floor in Chapel Hill
Chapel Hill · May 2026 · Chris & Nick · From our service records
What we found and did
Nick and Chris found a large grease block inside a 2 inch PVC drain line running beneath the concrete slab of a home in the 27517 area. The team removed a 3 by 3 ft. section of flooring and concrete in the living room to reach the line, cut the 2 inch PVC, and cleared the grease block with pressurized water. They then ran a milling machine through the line to help ensure future quality of drainage, followed by a sewer camera to confirm the grease was cleared around the pipe walls. Afterward, the area was backfilled to a rough state so property management could repour the concrete and repair the flooring.
Result
The sewer camera confirmed the grease was cleared, and running high-pressure water down the system along with the kitchen sink showed everything draining properly.
