FIELD: sewerage.
SUBSTANCE: invention relates to sewage equipment. Device comprises tubular element (1), on one end of which there is flange (11) and outlet (10) communicating with said device for discharge of drained water, nut (2) configured to interact with tubular member for connection of drainage assembly in assembly with sanitary instrument, drain neck (3) made with possibility of connection with the above tubular element, at least one drain pipe (4) coming out of drain neck (3). Nut (2) comprises retainer for attachment of drain neck (3). Drain neck (3) is characterized by availability of the area for arrangement of the lower part of the nut. Nut has a screwing axis, around which passes said lower area, characterized by the presence of part of a conical or spherical shape, designed to interact with location area, thus providing possibility of drain neck (3) rotation relative to nut (2) around at least one axis of rotation, perpendicular to axis of screwing and perpendicular to drain pipe (4).
EFFECT: fast and simple assembly of a device characterized by high mechanical resistance and tightness maintained over time.
