.....what a pia! Bathroom redo in a 1960's built house. Of course, the 1-1/2" bath sink drain pipe is cast iron and the pipe sticks out of the wall under the bath sink about 5". The threads have gunked up somewhat and I cannot get either of the 2, pvc/plastic nut to screw on nor a galvanized cap (thinking I could use this to clean up the old threads). Questions ....is HOW to REFRESH the threads on this OLD pipe cleaned up to ACCEPT a new screw on adaptor?? Thanks in advance!!
