How do you cut into a 4in. cast iron drain pipe for a sink drain?

The easiest way is to rent a pair of cast iron cutters from the rental shop. I have used a hack saw (not easy) and a sawsall. Make sure to cut it straight and if the pipe is on the vertical make sure it is supported so the weight of the pipe does not pull it apart. Use no-hub couplings (also called a fernco coupling, Caulder coupling) to attach fillings and pipe to the cut cast iron.

Good Luck

Cool

For illustrated how-to go to http://www.bhglive.com/homeimp/ and follow the links in the Plumbing section to "Roughing In" and "Tapping Into Cast Iron Drain Lines".

(This is what John is referring to.)
Good Luck!
