      When installing a new ABS joint in my cast iron stack. I noticed that only 2 inches of the 4 inch stack diameter is clear of buildup throughout. I am wondering if using an auger would damage the cast iron pipe, seeing as the buildup has occured over 100 years, or if I can simply clear some of this out without worry. Thanks!

      I would clear the drain out using hot water and a auger.

      If you see spots on the outside of pipe that looks like it has leaked, you might be better off not augering.

      Replace the soil pipe and then auger the rest of the pipe.
