The present invention concerns a pipe branch piece for use in a wastewater downpipe in a multi storey building. The piece branch piece includes a conduit body configured to form a junction between an upper downpipe portion, a lower downpipe portion and at least one supply pipe from a storey of a multi-storey building. The pipe branch piece further includes a flow path defining member configured to longitudinally extend within the conduit body in a substantially vertical orientation to define a first flow path for wastewater flowing from an upper inlet opening to an opposed lower outlet opening and a second flow path for wastewater flowing from at least one supply pipe inlet opening to the lower outlet opening. The pipe branch piece includes a deflecting region located directly beneath the inlet opening and formed from an upper portion of the flow path defining member. The deflecting region includes at least one diverting protrusion protruding upwardly from the deflecting region and configured to at least partially divert wastewater flowing across the at least one diverting protrusion. The deflecting region further includes at least one ventilation passage defined at least partially beneath the at least one diverting protrusion and configured to enable air pressure equalisation between the first flow path and the second flow path.
