  • a pop-up waste set comprising a valve body having a seal member and a float cooperating with a valve seat, the valve body having the seal member from the valve seat along a central axis from a rest position to a scavenge position and from the scavenge location is movable to the rest position, and a float chamber having an opening through which the valve body extends through and is movably supported therein, wherein the float is movable within the float chamber along the central axis and hydraulically cooperates with the float chamber.
  • the float chamber includes at least one control passage through which, as soon as a flushing water level surrounding the drain assembly has dropped to the level of the control passage, air from areas outside the float chamber may enter the float chamber such that the pressure ratios between the float chamber and the areas outside the float chamber can be compensated are, wherein the float is movable in balancing the pressure conditions of the scavenge in the rest position.
  • the float chamber has a base portion extending completely around the central axis and a snorkelling portion adjoining the base portion. The cross section of the snorkel section seen transversely to the central axis is smaller than the cross section of the base section. The float extends with a column section into the snorkel section.
  • the volume of the float chamber can be increased by arranging the snorkel section with a smaller cross-section than the base section, without adversely affecting the size of the drain fitting or its function. This has the advantage that a simplified optimization of the closing process is made possible due to the increased volume.
  • the float preferably has a lower portion, wherein the lower portion is formed substantially circular cylindrical and in the filling position preferably fills or substantially fills the base portion of the float chamber.
  • the column section is preferably designed as a float.
  • the column section like the lower section, is substantially formed as a cavity filled with air.
  • kel section is understood to mean a section which supplements the base section in the installed position at the top.
  • the base portion is preferably formed circular cylindrical.
  • the snorkel section lies within the maximum diameter of the base section.
  • the outer shape of the float with the lower portion and the pillar portion and the inner shape of the float chamber with the base portion and the snorkel portion are such that the float is movable in the float chamber.
  • the two forms are substantially matched to each other, optionally with play to each other, formed.
  • the cross-section of the column section fills the cross-section of the snorkel section substantially completely or at least 55%, in particular at least 75%. That is, the column section extends in cross section transversely to the central axis substantially completely or almost completely over a major part of the cross section of the snorkel section.
  • the column section fills the volume of the snorkel section in Essentially complete, or at least 55%, or at least 75%, when the float is in the rinse position.
  • essentially completely means that the column section and the snorkel section are positioned relative to one another in such a way that there is always a residual amount of water between the column section and the snorkel section.

  • the column section and the snorkel section are offset from said central axis laterally to the central axis. That is, the snorkel portion is arranged eccentrically to the lower portion and the column portion is arranged eccentrically to the base portion.
  • play is present between the outer sides of the column section and the insides of the snorkel section.
  • the float chamber ie the snorkel section and the base section, apart from the at least one control passage, is formed so as to be completely closed laterally to an end wall with a side wall. At the bottom, the float chamber is open. In the end wall, the bearing opening is preferably present, in which the valve body is movably mounted.
  • At least one of the outer sides of the column section is inclined at an angle to the central axis.
