: I have remnmove the old flange which was LEaded into the Cast drain pipe. The inside diameter of the drain is 4 1/4 inches. I tried to fit a 4 inch PVC flanfe in the hole with a rubber ring. it was to small. My question is do they make a PVC Flange or larger Rubber ring that will fit this opening. Or, Can you lead a PVC pipe into the cast drain?

: Thanks,

I would get a 4" inside Caulk cast iron flange and re caulk it Or if to do not like caulked try to get a NO hub Quick set cast iron floor flange and these come in various lenths and you can make a perfect water/gas tight joint OR try this as I used it over a 4" galvanized soil line and it worked great.
