Watch our video below for guidance / how to change your Quarter turn ceramic valves.



Replacement spares compatible with the CDA TC77 kitchen mixer tap.

Original part code SP3308 3308R

If your tap is dripping or leaking out of the spout then it is time to replace / change the quarter turn ceramic disc cartridges. Hot and cold valves available

The TC77 Cartridge has 28 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"

How To remove the TC77 tap handle: there will be a grub screw on the underside of the handle. If you require an allen key to remove the handle then you can purchase our Allen Key Pack (SK01_S). The handle will then pull off.

Your tap handle may utilise a plastic handle adaptor / tap head carrier. Sometimes this can wear or break and we can supply this part if you require a new one (Our part SA03_S). Original tap handle adaptor code SP3530

How to remove your cartridge _ Our Cartridge Valve removal tool (ST03) is available to enable easy removal and fitting of the cartridges which are recessed into the tap body. The old valve may have two flats instead of a hex nut. Our tool has two ends. One end to remove the cartridge with two flats and one end to remove/fit new cartridge with hex nut.

If your TC77 tap is leaking around where the swivel spout joins the tap body (the neck) you need to replace the spout O 'Rings.

How to remove the TC77 Spout?
Use 2.5mm allen key to undo grub screw at the back of the spout. Pull spout up and away from the tap body. Replace O'Rings. Apply silicone grease (suitable for potable water) to the new O'Rings.

We supply a replacement aerator/antisplasher which is our Code SR24C-S.
