How to Troubleshoot Common Problems After Pipe Relining

by

Pipe relining is a popular method for repairing damaged or aging pipes without the need for excavation. While it is generally effective, some homeowners and contractors encounter common problems after the relining process. Knowing how to troubleshoot these issues can save time and money, and ensure the longevity of the repair.

Common Problems After Pipe Relining

  • Reduced water flow or blockages
  • Unusual odors emanating from drains
  • Leaks or water seepage around the relined pipe
  • Cracks or damage to the relining material
  • Persistent backups or slow drains

Identifying the Issue

The first step in troubleshooting is to identify the specific problem. Conduct a visual inspection if possible, or use a CCTV camera to inspect the interior of the pipe. This will help determine if there are blockages, cracks, or improper lining.

Troubleshooting Steps

  • For Blockages: Use a drain snake or hydro-jetting to clear debris. If the blockage persists, inspect for improper lining or obstructions.
  • For Odors: Ensure proper venting of the plumbing system. Clean or replace any damaged sections of pipe or lining that may harbor bacteria causing odors.
  • For Leaks: Check for cracks or holes in the relining material. Minor leaks may be repaired with epoxy or lining patch kits, but significant damage may require pipe replacement.
  • For Damage or Cracks: Schedule a professional inspection. Minor cracks can sometimes be sealed, but extensive damage may necessitate relining or excavation.
  • Persistent Backups: Confirm that the relining was properly installed and that the pipe diameter is adequate. Consider professional cleaning or re-lining if necessary.

Preventative Measures

To minimize future problems, regular maintenance is essential. Schedule periodic inspections, avoid flushing non-degradable items, and be mindful of what enters your drainage system. Proper installation by experienced professionals also reduces the likelihood of complications.

When to Call a Professional

If troubleshooting steps do not resolve the issue, or if you notice significant damage or persistent problems, it is best to consult a licensed plumber. Professionals have the tools and expertise to diagnose and repair complex pipe issues safely and effectively.
