Sewer Line Replacement Services in Southern California

What Is Sewer Line Replacement?

Sewer line replacement, or sewer repiping, is the process of removing old, damaged, or collapsed sewer pipes and installing new, durable lines to restore proper drainage. While minor issues can sometimes be repaired, replacement is the best long-term solution for pipes that are cracked, corroded, or repeatedly clogging. At Repipe Once, we use proven methods and high-quality materials to ensure your new sewer system runs smoothly for decades, protecting both your property and your peace of mind.

Signs You May Need Sewer Line Replacement

Sewer line issues often start small but can quickly escalate into major damage if left untreated. Watch for these common warning signs that it may be time to replace your sewer line:

• Frequent Clogs or Backups – Multiple drains in your home or business backing up at the same time often point to a main sewer line problem.
• Slow Drains Throughout the Property – Consistently sluggish drains signal restricted flow in the sewer system.
• Sewage Odors – Foul smells inside or outside your property may indicate a broken or leaking line.
• Pooling Water or Sewage in the Yard – Wet, soggy areas or unexpected patches of lush grass can be a sign of a sewer leak underground.
• Cracks or Damage in Foundation – Leaking sewer lines can wash away soil, leading to structural damage over time.

If you notice one or more of these issues, a full sewer line replacement may be the safest and most cost-effective solution.

Benefits of Sewer Line Replacement

Replacing an aging or damaged sewer line isn’t just about fixing a problem — it’s about protecting your property and ensuring your plumbing system works the way it should. Key benefits include:
