Help Connecting New Drain to Existing Cast Iron Hub
Recently removed an old sink in the basement to find that the drain for that sink and the drain for the kitchen sink above just let out into an old 4-5" diameter cast iron drain pipe raised about and inch from the concrete floor. No fittings/couplings, just loose. I'm not a plumber but I know that's not right. I'm looking to replace the sink and tie into the pvc line coming from upstairs. However, I need a way to seal it onto the cast iron? How do I connect a 2" pvc line to a 4-5" cast iron line (all waste, no rain or groundwater)?
