Abstract
A plumbing network section for multi-storied construction is disclosed which uses an integral waste stack segment and waste receiving manifold for receiving waste from plumbing fixtures, and with multiple vents in the waste receiving manifold arranged for connection to a vent manifold. The combination waste stack section and waste manifold, and also the vent manifold uses sleeve type construction for connection to pipes which simplifies assembly in the field and effects reduction in labor and parts costs.
