We did some remodeling and our contractor roughed in a bathroom for us in our basement. They weren’t able to finish it off because the ceiling is too low to meet code for a bathroom but we planned to finish it ourselves anyway. Where the sink will go, we have the two copper pipe stubs that we will put valves on but we have two pvc pipes coming out of the wall and we are unsure why there are two? I assume one is for the drain but can’t find anywhere why we have a second one??
