The CLICK cartridge offers water saving by encouraging the user to only lift open the handle before coming against slight resistance. This resistance informs the user that the fitting is delivering only 50% of its maximum flow potential. Lifting the handle beyond the resistance enables the fitting to deliver flow at maximum level. The cartridge also features a limiting device that can restrict movement of the handle on the hot side, adding a major safety feature. Flow rate with fitted regulator 5 litres per minute. Unregulated flow rate 5 litres per minute at 0.1 bar.
