Hello all,

I'm starting down the path to redo my one full bathroom in an older (1920s) house. In planning it out, I have determined that the drain from the toilet is cast iron. My plan includes moving the toilet, which I know means I have to move the drainage as well. Should I expect to run into any additional complications because I will be dealing with a cast iron pipe instead of PVC? How do older cast iron drains usually attach to each other? Is it the same metal type rings that are used today?

Thanks!

Older cast iron pipes are joined together with molten lead and a sealing type rope called oakum.
You can join your PVC to a piece of cast iron with one of the metal clamps you mentioned that is called "A No Hub Connecter". But first you have to cut the Hub off the cast iron so that it is the size of the PVC.

Cutting cast iron doesn't exactly sound like something I want to tackle. I'll hire someone for that part :)

Thanks!
