Do Home Inspectors Check Sewer Lines?

A home inspection is a crucial step in the home-buying process, providing valuable insights into the property’s condition. One common question is whether home inspectors check sewer lines, and the answer is typically no, but here’s a comprehensive analysis.

Standard Scope of Home Inspections

Home inspections generally focus on readily accessible and visible components of the home, including:

  • Roof
  • Exterior
  • Structure
  • Electrical system
  • HVAC system
  • Plumbing fixtures and appliances
  • Insulation and ventilation
  • Interior finishes

Sewer lines are typically buried underground and not readily accessible during a standard home inspection.

Factors Influencing Inspection Scope

However, certain factors may prompt inspectors to investigate sewer lines further, such as:

  • Visible signs of problems: If the inspector notices leaks, backups, or other issues with plumbing fixtures or appliances, they may recommend further evaluation.
  • Age and condition of the house: Older homes or those with known plumbing issues may warrant a more thorough inspection.
  • Specific buyer requests: Buyers may request additional inspections, including sewer line inspections, for peace of mind or insurance purposes.

Additional Considerations

  • Video camera inspection: If the inspector recommends further evaluation, they may use a video camera to inspect the sewer lines. This provides a detailed view of the interior of the lines, identifying any blockages, cracks, or other issues.
  • Smoke testing: Another technique is smoke testing, where smoke is pumped into the sewer lines to detect leaks or other problems.
  • Cost: Additional inspections, such as video camera inspections, may incur additional charges.

Importance of Sewer Line Inspections

While not typically included in standard home inspections, sewer line inspections are highly recommended for certain situations. A poorly functioning sewer line can lead to:

  • Plumbing issues (e.g., backups, leaks)
  • Health hazards (e.g., contaminated water, sewer gas)
  • Property damage (e.g., flooding)
  • Expensive repairs
