Valve arrangement comprises return flow preventing units (30, 44) and a bleeder valve forming a removable one-piece component (10). The bleeder valve forms a valve slide (16) which is impinged on a front surface by the drinking water pressure and on the opposite side by the pressure in the space between the return flow preventing units and by which a run-off opening of the tube separator laterally connected to a run-off is covered in its closed position. Preferred Features: The valve slide is arranged isoaxle to the return flow preventing units. The valve slide has a cylindrical casing surface and can be guided with the casing surface into sealing rings held in the pipe separator housing (12). |
