I have searched through the NPC for the rules of burying copper drinking water supply lines.
The only reference I have found is in the screen capture attached referencing mechanical damage.
Wayne had sent me the IPC rules for burial but I cant find anything even close in the NPC:
305.1 Protection Against Contact
Metallic piping, except for cast iron, ductile iron and galvanized steel, shall not be placed in direct contact with steel framing members, concrete or cinder walls and floors or other masonry. Metallic piping shall not be placed in direct contact with corrosive soil. Where sheathing is used to prevent direct contact, the sheathing shall have a thickness of not less than 0.008 inch (8 mil) (0.203 mm) and the sheathing shall be made of plastic. Where sheathing protects piping that penetrates concrete or masonry walls or floors, the sheathing shall be installed in a manner that allows movement of the piping within the sheathing."
The reference is to this installation job.
thanks!!
