I have to put in a new sink disposal in my kitchen sink. The drain pipe coming out of the wall is copper. Can I cut the exsisting brass trap out and replace it with a PVC trap and attach it to the copper wall drain pipe. The wall drain pipe also has a threaded brass ring that I would cut off to accommodate the PVC trap. I dont know whether it is acceptable to combine PVC and copper or does it have to be brass and copper. Thanks Dave G
