In a practical test, Geberit Acanto is rated the best WC ceramic appliance with rotational flushing. The model stands out in particular when low water volumes are used.

How good are WC ceramic appliances with rotational flushing? SBZ, the German specialist magazine for the HVAC and plumbing industries, wants to find out. In collaboration with the Esslingen University of Applied Sciences, ten models from renowned manufacturers are tested in which the flush water flows through the ceramic appliance in a rotational movement. The focus is on flush quality and hygiene.

The independent experts from the Esslingen University of Applied Sciences come to the conclusion that rotational flushing systems are superior to conventional flushing systems. Geberit Acanto with TurboFlush technology impresses with top scores in all test categories, from the flush tests with toilet paper and plastic balls through to smear tests with ketchup. In the overall ranking, Acanto clearly beats its competitors.

Clean flushing out with low water consumption

The clear top performance of the Geberit ceramic appliance in the flush tests with reduced water volumes is particularly pleasing. “It is remarkable that the Acanto model retains its effective combination of rotational and downward flow even when the partial flush is used,” says Professor Philipp Akkawi from the Esslingen University of Applied Sciences. “This represents a significant step forward in water-saving sanitary technology.”
