What Makes a Sewer Lateral Fail Inspection, and Which Repairs Pass It?
By The Otter Squad·Published 2026-09
If your district requires a lateral compliance certificate, the line has to pass an inspection — and sometimes a pressure or air test. Here is what typically fails, and what it takes to pass.
Defects That Commonly Fail
- Cracks and fractures in the pipe wall
- Root intrusion at joints or through cracks
- Offset or separated joints that leak under test
- Bellies (low spots) that hold standing water or solids
- Collapsed or badly deformed sections
- Inflow / infiltration that fails a pressure or air test
Repairs That Bring It Back to Passing
Not every failure needs a full replacement. Depending on what the camera shows:
- A single isolated defect — a targeted spot repair can pass.
- Widespread cracks or root intrusion in a still-round pipe — CIPP lining installs a seamless new pipe inside the old one.
- Collapsed or deformed sections — pipe bursting replaces the line with new HDPE.
The right fix depends on what the camera shows and what your district's test requires. We show you the footage, explain which option passes, and give you upfront pricing for each.
