Abstract

In order for it to be possible for cistern water to be freed more easily from suspended particles which have collected in a floating layer, and also in order to realize an easy-to-produce filter housing of straightforward construction for a rainwater filter, it is proposed to provide the filter housing, which has a cylindrical outer lateral surface and a base (14), with a first outlet (10) for the filtered water and, in the centre of the base (14), with a second outlet (12) for the non-filtered, contaminated water, this second outlet being connected to a drainage pipe (18). The drainage pipe (18) has a portion which runs parallel to the base (14), the wall of this portion, above the base, containing an opening (20) which serves as a cistern overflow.
