How to Change a Water Filter Cartridge in a Couple of Minutes

Changing a water filter cartridge is super easy. No need to call the plumber. And it can be done in a couple of minutes.

Step 1 - Removing the Old Cartridge

You’ll need:

  • A dry tea towel
  • A new water filter cartridge


Place the dry towel under the filter cartridge. Turn off the cold water under the sink and turn the mixer tap on. This releases pressure in the system and makes it easier to remove the water filter cartridge. Then twist to the left and pull. The cartridge comes off easily.

A little excess water may come out of the head. Just wipe this up with the tea towel.

Step 2 - Fitting the New Cartridge

Take your new cartridge. Place it in the head and line up the cartridge lugs.

Then give it a good push and twist to the right. Now it’s locked in and ready to go.

Please Note: With the aim of reducing the amount of plastic going into landfill WFA recently introduced an automated annual cartridge replacement email reminder service.

As such, we will no longer be supplying the alarm monitor with each replacement water filter cartridge.

Your tap should then be running filtered water at full flow. Let the water run for 1-2 minutes to activate the water filter cartridge. Then it’s ready for all your kitchen needs.

Changing a Premium Water Filter Cartridge

It’s the same procedure for changing a Premium filter cartridge. You still need to turn the tap off underneath the sink and run the separate tap instead of the mixer tap to clear any pressure.
