Hello.. I'm redoing a bathroom and have to replace a section of 1-1/2" galvanized drain pipe, which runs horizontally before it meets the main cast iron stack. Now, I was able to remove all of the galvanized pipe and found a 1-1/2" PVC threaded male coupling that will thread into the cast iron hub. My question is whether this will work, and if so what type of sealant I should use on the threads? Thanks for the help-
