How do I change the cartridge on this tap?

[Shane]

Our bathroom vanity mixer tap is leaking when over on the cold setting. Strangely, when we leave it on the hot position like in this photo it is OK. 

I assume I need to replace the cartridge but don't know how to get to it. Anyone got any ideas?

Hi @Shane,

Under the handle section, there should be a little cap or hole which has an allen key screw inside it. Once you have undone this screw the handle will come off which will give you access to the ceramic disk cartridge. Take the cartridge into your local store and a team member should be able to match it up for you.

Please let me know if you run into difficulties or had questions.
