Abstract

A waste outlet fitting (1) has a tubular body (2) in which a cartridge (3) is mounted. An elastomeric diaphragm (6) is carried by a central support member (4) integral with the cartridge and defines a skirt flaring outwardly to normally close the bore of the cartridge (25) and thus the tubular body (2). Part of the cartridge wall may be elastomeric for improved sealing with the diaphragm (6). Pressure of water leaving a basin via the outlet fitting (1) causes the diaphragm to deflect downwardly and inwardly allowing water to pass. When the basin is empty the diaphragm (6) returns to its original position under its own resilience, thus sealing the outlet from any back flow. <IMAGE>
