I have cut out a section of the existing basement wall, and there is a sheet of plastic between the drywall, and the studs. One of the drain pipes is on the outside of this sheet between the concrete wall, and the sheet. Can I put my copper pipe there? What about the insulation that is there, will that affect the copper? Or do I have to keep the copper on the inside of the sheet between the sheet and the drywall? Is there and code issues with this? Can the copper pipe "touch" insulation, the sheeting, or the drywall?
