Abstract

Double backflow preventer in a water gully, which is conically designed as a rotatable pot with outer and inner pot (16, 17), the end of greater diameter being directed towards the water backflow and being sealed off by means of a backflow preventer (25), and the casings of the pots (16, 17) each being provided with an opening (20, 21) which can be sealed off by turning. The double backflow preventer, which at the same time forms an odour seal, is inserted, and releasably fastened, in the water-discharge tank (10). <IMAGE>
