  1. 1

    Turn off the water supply to the faucet from under the kitchen sink. There should be two small valves, turn the handles clockwise until the water stops.

  2. 2

    Remove the Europlus II faucet handle with a 3mm Allen wrench. A wrench should have been included in the original faucet packaging.

  3. 3

    Unscrew the top of the faucet, or faucet cap using your hand or a plumber's strap wrench. Do not use sharp edged tools; you will ruin the faucet's finish.

  4. 4

    Remove the two screws holding the faucet's ceramic disc cartridge in place with a screwdriver.

  5. 5

    Remove the cartridge and inspect the casing, O-rings and gaskets for damage. You can replace the O-rings and gaskets, but it is sensible to replace the whole cartridge while you have the faucet apart.

  6. 6

    Install the new Grohe faucet cartridge by lining up the screw holes on the cartridge with the holes in the faucet body. The cartridge only installs in one direction.

  7. 7

    Reinstall the cartridge retaining screws, top cap and handle.

  8. 8

    Turning the water back on and test the faucet several times. Inspect the faucet for leaks around the handle, base and spout.

  1. 1

    Remove the spout aerator with a 24mm socket wrench. Rinse the aerator under warm water in the bathroom sink, taking care not to lose any small faucet parts down the drain.

  2. 2

    Remove and clean the faucet cartridge. If there is a hard, white mineral build-up inside the faucet body, use a small piece of emery cloth to sand it clean. Wipe the inside of the faucet to remove any debris. Replace the Grohe ceramic disc cartridge.

  3. 3

    Disconnect the water supply lines from the faucet and test the water flow. Turn the water off to the faucet, and then remove each supply line one at a time with an adjustable wrench and slip joint pliers. Aim the open end of the supply tube into the bucket and turn the water on. If there is low water pressure or volume, replace the shut-off valve. Reconnect the supply lines.

Tips and warnings

  • Don't use Teflon paste or tape to seal leaks; you can easily clog the small orifices of the Europlus II ceramic disc cartridge.
  • Do not over tighten the screws or top cap; you will irreparably damage the faucet.
