The joystick handle of the faucet is connected to the discs by a patented fixation system – GROHE uses solid metal for strength and durability. As the discs move over each other, they either block the water or allow it to pass through. Therefore the quality and machining of these parts will affect the performance of the faucet.
GROHE is one of the world’s leading faucet manufacturers. Our cartridges are manufactured in a high-tech process and feature discs made from a space-proven ceramic alloy. The polished mirror-like surface of the discs is then coated with a special lubricant for frictionless operation. And because our faucets are designed to withstand years of use, we incorporate micro-chambers of this lubricant within the cartridge – for a lifetime of maintenance free operation.
