I am trying to remove several 2" galvanized fittings / nipples from our kitchen sink drain assembly. They are quite rusty, possibly as old as 60 years. I can just barely get a pipe wrench on it, but working inside the kitchen base cabinet cannot get too much leverage.
Any tips for how to remove these fittings? Any hope for penetrating oil? There is about 1/4" inch of nipple visible between the fittings. If I saws-all off the nipple, any chance I will have success removing the remainder of the nipple from the female fitting in the wall? I'd like to get back to the female fitting in the wall, and start fresh with a PVC male adaptor.
Thanks very much for any suggestions.
