i got the dorf veus kitchen mixer leaking i purchased the catridges ?

The cartridges will be handed - one for hot and one for cold.

Turn off the water supply - remove the top cover - use a spanner to remove the cartridge - put in the new one - put the lid back - turn on the water - have a cup of tea - do the one on the other side. An easy task.

Good Luck...
