The latest generation of LAUFEN water-saving WCs is optimized to flush with two reduced flushing volumes: 4.5 or 3 liters of water. Compared to today’s 6/3 liter dual flush or 6 liter single flush standard, these new models provide substantial water savings. With an average of 5,000 flushes per WC per year, the yearly water saving is at least 6,000 liters or more than 27,000 liters if we take into consideration that 9 or even 12 liter models are still in use.
LAUFEN products that are marked with the green 4.5/3L logo are not only fulfilling the requirements defined in the harmonized standard EN 997 Class 1 Type 5 and Class 2 (that cover the whole European territory), but also fulfill the challenging Australian requirements of SAI/Wels 4 Stars.
In order to achieve this water saving option, the LAUFEN floor-standing WC combines with its dedicated container having the option of .75x. LAUFEN wall-hung or floor-standing WCs shall be combined with any concealed cistern, locally available and approved for 4.5/3 liter flushing.
Please note that a suitable downstream drainage system must be built for this kind of water-saving WC. In case of restrictions in the existing drainage system or local regulations, LAUFEN WCs marked with the green 4.5/3L logo can also be flushed with standard 6 liter flushing volume.
