14 liters One Family Booster
Prevent problems and save up to 40% on water consumption
WISA Water Saving Technology enables you to reduce the amount of water used for flushing the toilet by 40%. Thanks to the combination of a WISA XS 4L Dual Flush built-in system and the WISA Booster, only 4 or even 2 litres of water are needed to flush the toilet. This results in an annual saving of approximately 12,000 litres of water per household.
WISA Water Saving Technology is a sophisticated sewer system that consists of three components which are carefully aligned to ensure a smoothly functioning system. The first component is the Booster, which arranges the transport of water through the branches. The second crucial component is the 4-litre flushing system, and the third is the 4-litre wall-mounted closet.
