The drainage has a cup-shaped drainage housing (1.1), which has connection free base component (1.2) formed in jacket or cup shaped. The drainage has a connection (1.5) arranged laterally and has an inlet opening (1.3) at its upper side. The base component is connected with the drainage housing in height adjustable and liquid-tight manner. An immersion nozzle (2) is formed from two pipe sections (2.1,2.2), which are coaxially rotated or slid together for changing an axial length of the immersion nozzle. |
