The mixer tap must be connected in a pressure-tight manner in order to connect to it then connect the shower hose to the outlet nozzle

This also results in considerable heratel and Storage simplifications, as the previous spatial shapes of the mixer taps can be retained.

FIG. K shows a further pipe aerator to be assigned to the mixer tap according to FIG. 2.

Both pipe ventilators have a housing 1 with two connecting pieces 2 and 3 running at right angles to one another. While the nozzle is 3 ausnehilriet as a threaded socket for connecting a ErsiissschlsiiCheAnschluSysrsGhrsuiJiing k. the connector 2 serves for the pressure-tight connection of the housing to a threaded connector of the mixer tap 5. In addition, a nipple 7 is screwed pressure-tight into a threaded hole G of the housing 1, on which a union nut 8 is rotatably mounted.

Furthermore, in the housing 1 είπε ventilation chamber 3 is formed, in which a valve body 11 which closes by gravity and which corresponds to a valve seat 10 is mounted.

The valve seat opens into the open air and is on one in one second threaded hole 12 of the housing 1 screwed pressure-tight Socket 13 integrally formed.
