Sewer Line – Inspect, Educate, Protect

What type of sewer line do I have is one of the most common — and most important — questions New Jersey homeowners ask when dealing with slow drains, recurring backups, or preparing to buy or sell a home. Your sewer line material directly affects maintenance requirements, expected lifespan, and the likelihood of costly repairs.Older infrastructure throughout New Jersey means many homes still rely on aging clay or cast iron sewer lines. Understanding your sewer line type allows you to plan maintenance proactively instead of reacting to emergencies.

Why Knowing What Type of Sewer Line You Have Matters



If you are asking what type of sewer line do I have, you are already ahead of many homeowners. Different sewer materials deteriorate in different ways, and problems often develop underground long before symptoms appear inside the home.

Knowing your sewer line type helps you:

  • Anticipate material-specific failures
  • Schedule appropriate inspections and maintenance
  • Avoid unnecessary chemical or mechanical damage
  • Budget for future repairs or replacement
  • Reduce surprises during real estate transactions

How to Identify What Type of Sewer Line You Have

1. Check the Age of Your Home

Homes built before the 1970s commonly contain clay or cast iron sewer lines, while newer homes typically use PVC or ABS.

2. Review Property Records

Previous inspection reports, plumbing permits, and municipal records may list sewer materials.

3. Inspect Accessible Piping

Exposed piping in basements, crawl spaces, or near cleanouts may provide visual clues based on color and texture.
