Abstract

The object of the invention is a flush water outlet valve intended for the cleaning of filter materials in a water purification basin, which flush water outlet valve consists of a fixed lower tube (11) and a movable upper tube (10), over the edge of which the foul water is led to the outlet tube (33), and the filter materials consist of substances with different density, e.g. sand and absorbent carbon layers (4, 5). For the cleaning of the materials according to the invention, the movable tube (10) is placed inside the lower tube (11) movable so that the movable upper tube can be adjusted according to the sedimentation of the filter material. <IMAGE>
