If your tap is dripping or leaking out of the spout then it is time to replace / change the quarter turn ceramic disc cartridges. Original cartridge may be chrome and stamped with the code BS4512 CD XZ 20.

Cartridge has 20 teeth on spline. You will require our Anticlockwise open cartridge for the cold side, and clockwise open for the hot side, If you require both then you can select "Pair"

The Quest handle is held on by a plastic spline adaptor. How to remove the handle: The Handle will pull off. Unfortunately we do not supply this adaptor. As long as it is not broken you can re use this on the new cartridge from us.
