How to change Cartridge in your Single Lever Kitchen Tap

Just follow the 11 easy steps below to replace cartridge in your Single Lever Kitchen Tap:

  • Step 1: Make sure to turn OFF the hot and cold water mains as otherwise water will come out of the side of your tap once you access the cartridge.
  • Step 2: To remove the handle you must remove the grub screw with a suitable sized allen key.  Be careful not to lose grub screw. Some Single Lever Taps have a coloured indicator on the front (blue / red) which conceals the grub screw. Remove this indicator carefully with something delicate e.g. tip of knife, being careful not to scratch your tap to access grub screw behind.
  • Step 3: Unscrew the silver dome shape. Turn AntiClockwise to loosen.
  • Step 4: Use an appropriate sized spanner (or adjustable spanner) to loosen the Brass Nut. Turn AntiClockwise to loosen
