Short answerNot necessarily, but they deserve a look. Cast iron drains in older homes can rust through and crack over time. Orangeburg, a fiber pipe used for some sewer lines in the mid twentieth century, can deform and collapse. A sewer camera scope shows the condition. Repairs range from spot fixes to full line replacement.
What do inspectors check?
Inspectors spot cast iron in basements; sewer lines need a camera scope.
What are the common findings?
- Cast iron was common before plastic drains. Orangeburg was used for some sewer lines from the 1940s into the 1970s.
- Rarely an insurance issue, but backups can be costly.
How serious is it?
The risk is leaks, backups, and collapse.
