The Viega concealed cisterns 2H, 2C and 2S with 1130 mm construction height will be equipped with a flushing throttle as standard in future. This means the flush rate can be reduced without reducing the flush volume. Thanks to the new flushing throttle, splashing over rimless WC ceramics is now a thing of the past. The device has five settings for adjustment to the respective situation. Viega cisterns that are already installed can be retrofitted in a few minutes.
The range of different looks displayed by modern WC ceramics is just one aspect of their design. There are also technological aspects to be borne in mind, especially the fluid dynamics. This means that water can splash over rimless toilet bowls.
To prevent this and the resulting aesthetic and hygienic problems from happening in the first place, Viega concealed cisterns of type 2H, 2C and 2S with 1130 mm construction height will be equipped with a flushing throttle in the drain valve seat as standard in future. The factory setting will allow the maximum flow rate without reduction. However, the flow rate can be reduced without the use of tools. There are five possible settings: With a simple rotary movement, the throttle cross-section is reduced until no water splashes over the edge during flushing. The amount of flushing water stays constant, so the flushing effect remains the same as well.
The new flushing throttle is not only ideal for rimless WC ceramics, but also for special installations such as toddler and baby toilets in kindergartens. The throttle is also available as an individual article for retrofitting Viega concealed cisterns that have already been installed.
