Here is a photo of new construction inspection done yesterday. Gas for range on an island ran through the foundation. It was CSST tubing. No bonding observed. This is common for almost every home with a gas range top on an island. Many existing home have this same issue. Question is, " How can it be corrected?" I do not have this answer at this time. In order to run a gas line in concrete slab on grade it needs to be flexible material. With CSST concerns, what flexible material is safe? I do not mean Safe per the manufacturers?
Every Inspector needs to report these concerns to protect consumers as well as themselves.
