This diagram details the transition of six lines of pressurized 304 stainless steel waste or storm piping from the garage contractor to the mechanical contractor. The mechanical scope begins at the point of connection following a seismic connection provided by others. The piping run includes a backwater valve and transitions to a gravity connection that extends five feet outside the building exterior wall to the civil connection.
