Hello, replacing a kitchen sink and have a question. So my current set up is a double bowl sink but both sides are plumbed individually I think. The right side is a standard strainer that goes into a p trap to a wast pipe. On the left is the garbage disposal the goes into another p trap that's connected to a second wast pipe. That one sits lower than the other one. My question is since I'm going to a single bowl sink can I just cap off one of the waste pipes? Does it matter what one I use? I've tried to upload a photo but it keeps saying the file is to large.
