You’ll also find useful resources in our ‘How To’ section, featuring DIY guides on replacing valves, cartridges, and more. For example, check out 7 easy steps to replace a kitchen valve or how to replace a cartridge on your single lever tap—these can help you remove handles or levers to identify your tap parts before comparing them to ours. Browse our full range in the Tap Spare Parts section.

If you have the 28 spline, 3602R valve, then there has been a modification to this valve.
