1. How long do sewer lines last?

It depends on the material. Clay pipes may last 50–60 years, while cast iron lasts 75–100. Modern PVC pipes can exceed 100 years with proper care.

2. Can tree roots really collapse a sewer line?

Yes! Roots can crack pipes, block flow, and cause structural failure over time. Regular maintenance is your best defense.

Costs vary, but repairs can range from $1,000 for minor fixes to $25,000+ for full replacements. Contact KnightRooter for a free estimate.
