The persons engaged by the owner for installation shall indemnify the city and its authorized employees from any loss or damage that may directly or indirectly be occasioned by such installation.
(C) The building sewer, as defined in the State Plumbing Code, shall be constructed of cast iron, Type K copper, or non-metallic pipe meeting SDR 26 (ASTM 2241) or Schedule 40 or an approved equal wall thickness.
