Why a seller cares
Cast iron drains in a pre-1970s home rust from the inside, and a sewer scope is how buyers find out. A cracked line can cost five figures, so the finding usually becomes a credit request.

A simple example
Your 1958 home has original cast iron drains. The buyer's sewer scope shows scaling and a cracked section under the slab.
| What the scope finds | What tends to follow |
|---|---|
| Scaling, still flowing | A note in the report, sometimes a small credit |
| A cracked section under the slab | A repair quote in the thousands and a credit negotiation |
| Already replaced with PVC | A selling point worth putting in the listing |
Cast iron ages out of sight. The scope is where it becomes a number.

What people get wrong
That drains that work are fine. Cast iron can flow for years while it thins, and the scope shows the thinning.
