  • Flathead screwdriver
  • Phillips head screwdriver
  • Toothbrush
  • Vinegar
  • Bowl or container
  • Clean cloth

How to Remove a Tap Cartridge

1. Mix together warm water and a small glug of vinegar in your bowl or container.

2. Turn off both your hot and cold water using your boiler or isolation valves. Then, turn on the tap to allow any excess water inside to drain out.

3. Use your screwdriver to remove the head of your tap, then remove the nut underneath it. From here you can remove the tap cartridge using your spanner.

How to Clean a Tap Cartridge

1. Soak the cartridge in your mixture of water and vinegar for around 10 minutes to dissolve any limescale.

2. If you remove the cartridge and it still has limescale on it, soak it for longer. If this isn't working. add more vinegar to your mixture and soak your cloth in it and wrap it tightly around the cartridge. Leave this for an hour or two.

3. Using your toothbrush, gently clean around your tap to break down limescale. Remember to clean inside the tap and in the little orifices - then wipe clean with a cloth.

4. Check that every part of the tap is clean and free from limescale, including the washers and ring seals.

5. Put the cartridge back into the body of the tap, covering it with the nut.

6. Screw the tap head on with the screwdriver, being careful not to overtighten as this will damage the tap.

7. Turn your water supply back on and check there are no leaks. If your water was flowing badly due to limescale build up, it should now flow freely.
