Cast iron drains and pipe lining (the "sock")
Pipe lining fixes a cracked drain from the inside: a felt tube (the "sock") soaked in epoxy is pulled or blown into the old pipe and hardened into a new pipe inside the old one, usually without digging up floors.
What to look for
Warning signs
- Several slow drains at once
- Gurgling toilets
- Backups after heavy rain
- Sewer smell
- Roots or rust flakes in a camera inspection
Do it yourself
- Find the cleanout and keep it accessible.
- Use enzyme cleaner monthly. Never use chemical drain cleaner on old cast iron.
- Snake small clogs at the fixture.
- Get a sewer camera inspection and keep the video.

Pipe lining (CIPP sock)

Pipe bursting or replacement
$$$
For collapsed or flattened pipe: pull new pipe through the old path, or dig and replace with ABS or PVC.
