Abstract: A connecting pipe part of a resilient material for connecting a closet bowl to a drain conduit comprises on one end a female part for receiving an outlet of a closet bowl and on the other end a male part to be received into a drain pipe or conduit, while a sealing sleeve connected with the female part extends within the female part.Said sealing sleeve merges through a discontinuously thinned transition. Into the female part, the thickness of the sleeve being thinner than the thickness of the female part.The transition is preferably located halfway in a plane parallel to the inner wall of the female part, said plane being located midway between the inner side of the female part and the extension of the inner side of the male part.End part support members extend in the direction of the male part.

Abstract: A fluid distribution system comprises a fluid distribution conduit, a fluid inlet and a plurality of closeable fluid outlet branches. The distribution conduit further comprises a plug which can be propelled in response to the fluid pressure, whereas valves are provided with retaining means members for retaining the plug contrary to the fluid pressure for opening the valves. The retaining means become inoperative when the pressure of the fluid is being altered.
