Rangmaster Matrix valve we don’t have
Here is our Guide 7 Easy Steps to replace Kitchen Tap Valve.
Due to the valve being exposed to air at the manufacturing plant (oxidation), you might notice that the brass is slightly blackened in places. These are brand new valves direct from the manufacturer and the ceramic disc and seal are perfect. The slight discolouration has absolutely no bearing on the workings of this valve which have been tried and tested here.

- Genuine = Proper fit, tested by the Manufacturer
- Compatible = Not made by your Tap’s brand. May not fit or last.
We’ve seen compatible parts cause leaks or damage. Choosing genuine parts protects your tap and warranty.
