What Are the Disadvantages of Trenchless Sewer Pipe Lining?

Trenchless sewer pipe lining has disadvantages such as limited suitability, slight loss of pipe diameter, and harder future access for repairs or tie-ins. Most problems occur when the host pipe is severely collapsed, has major offsets, or multiple junctions that a liner can’t bridge cleanly. A liner always follows the old path; if the pipe sags, the sag stays. If you’re in the Denver area, a site-specific camera inspection is essential to confirm lining will last and meet local conditions.

When to be cautious:

• Not feasible with full collapses, severe bellies, or large joint offsets.
• Reduces internal diameter, which can affect flow on marginally sloped lines.
• Reinstated branch cuts can snag debris and make future service harder.
• External problems (soil movement, crushed sections) remain and may be harder to reach later.

Always get a camera inspection and flow assessment before choosing lining. <br/> Updated: 2026-05-25 <br/> Need help in Denver, CO? Call (303) 237-4406 or book online.
