  • a special feature is found in the hand basin 6 and the sink 9.
  • a riser section is provided in the area of the removal fitting, that is, the connection of the drinking water consumers 6, 9 to the secondary supply line 11, 12 is realized via an integrated in the withdrawal fitting riser section.
  • a removal module 27 is provided below the riser consumer 6, 9 between a free end of the secondary supply line 11, 12, which defines a connection point for the riser consumers 6, 9, and the removal fitting of the riser consumer 6, 9.
  • the removal module 27 is an angle valve 27 with integrated tapping point or sampling device. For complete removal of the drinking water in the area of the riser consumers 6, 9, the removal module 27 is opened.
