What are the common causes of a sewer line backup?

Common causes of a sewer line backup include tree root intrusion, heavy buildup inside the pipe, damaged or collapsed sections, and improper drain installation. Roots invading the main line and long-term buildup are frequent triggers that restrict flow. Our plumbers serve homes across the Palm Bay area and can verify the exact cause with a CCTV drain camera before we clean or repair. Backups from simple buildup are typically cleared, while collapsed or badly deteriorated piping may call for section replacement or a repipe.

Specific causes we diagnose:

• Tree roots penetrating the main sewer line, often cleared with hydro jetting up to 4,000 psi.
• Heavy debris or scale causing internal narrowing that leads to blockages.
• Corroded or failing cast-iron drains that restrict flow or collapse.
• Blocked or misrouted drains from poor remodel or installation work.
• Broken, leaking, or collapsed sections that catch debris and backflow.

Skip chemical drain cleaners and schedule a camera inspection to pinpoint the issue before it worsens. <br/> Updated: 2026-03-31 <br/> Need help in Palm Bay, FL?
