Sewer and water lines sleeved through foundation under two stories
Are there any concerns with sleeving water and sewer mains through a foundation under a two-story addition? When we hired our contractor, he was aware of both of these utility lines and planned to sleeve them. Now he hints that while the water and sewer can be sleeved through the foundation that it isn't the right thing to do. We suspect that he's trying to change the scope of the job but need an expert to advise us.
