Sewer lines are designed to last at least 75 years for most materials, including PVC, clay, cast iron, and concrete. This lifespan, however, can be reduced due to a variety of factors, including:
Installation errors
Soil conditions
What you put down your drain lines
Trees located near your underground sewer lines
When you notice an increase in clogs and slow drains, it’s time to consider sewer line replacement. This indicates that sewer pipe cleaning services are required.
