DECA SLIM represents a different kind of flush valve cover option, featuring a clean, innovative, low-profile design that adds value to the product. Although at first sight it seems to be only a matter of changing the cover, a completely new, more compact flush valve mechanism was required to develop the product. Besides the clean and smooth cover design, the valve mechanism was designed so that only a soft push of the button is required. The cover fixture system also had to be redesigned to simplify installation. A central button activates the unit, which can be round or square to suit the design of the bathroom’s other fittings. The materials consist of chromed brass and engineering plastics.
