A sewer line belly, also known as a sag or low spot, occurs when a section of the sewer line sags or dips, causing water and waste to accumulate in that area. This can lead to blockages, slow drainage, and even backups if left untreated. Repairing a sewer line belly typically involves addressing the structural issue and restoring proper flow. Here’s how the repair process might unfold:

  • Professional Assessment: Start by hiring a licensed plumber or sewer specialist to assess the extent of the belly in your sewer line. They will use specialized equipment, such as video cameras, to inspect the line and identify the location and severity of the sag.
  • Diagnostic Video Inspection: The plumber will insert a camera into the sewer line to visually inspect the belly and surrounding area. This allows them to accurately assess the condition and determine the best course of action.
  • Repair Options: Depending on the severity of the sag and the overall condition of the sewer line, the plumber might recommend one of the following repair options:
    • Hydro Jetting: If the sag is caused by a buildup of debris or grease, hydro jetting can help clear the blockage and restore proper flow. This involves using a high-pressure water jet to break up and remove obstructions.
    • Pipe Relining: In some cases, the plumber might recommend relining the affected section of the sewer line. This involves inserting a flexible liner coated with resin into the pipe and then inflating it to create a new, smooth interior surface. Once the resin cures, it forms a durable pipe within the existing pipe, correcting the sag.
    • Sewer Line Repair And Replacement: If the sag is severe and cannot be corrected through relining, the plumber might recommend excavating the area and replacing the affected section of the sewer line.
  • Cost Estimates: After the assessment, the plumber will provide you with cost estimates for the recommended repair options. The cost will depend on factors such as the extent of the damage, the repair method chosen, and the local labor and material costs.
  • Repair Process: Once you’ve decided on a repair method and received estimates, you can schedule the repair work. The process will vary depending on the chosen solution. For relining, the plumber will typically insert the liner, inflate it, and allow it to cure. For excavation and replacement, the damaged section will be dug up, removed, and replaced with new pipe.
  • Inspection and Testing: After the repairs are completed, the plumber will conduct a follow-up inspection and possibly another video camera inspection to ensure that the issue has been resolved and the sewer line is functioning properly.
  • Preventive Measures: To prevent future sewer line issues, consider implementing preventive measures such as avoiding flushing non-flushable items down the toilet, using drain screens to catch debris, and scheduling regular sewer line maintenance and cleaning.
