Re: Replace Galvanized Iron Pipes
I'd recommend a rubber coupling ("Fernco" is a well-known name) for joining PVC to iron drain pipes. Or, if the drain pipe provides a good threaded connector, you can use a threaded PVC connector.
As a rule of thumb, PVC, ABS, and iron all have the same outside diameter, known in the trade as IPS (Iron Pipe Size). There are exceptions: I think storm drain pipe used in exterior underground applications may be a different size.

I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
