How do I replace the cartridge in my shower valve?

The cartridge is the heart of your valve — it mixes hot and cold water and controls flow. Over time, it can wear, scale up, or seize. This can cause a dripping shower, uneven temperatures and stiff handles.

To ensure you have the correct instructions for removing the cartridge, please refer to the instruction manual provided with each product. These manuals can be accessed by finding the relevant product in our website and navigating to the 'Downloads' tab on the product page.

Tip:

Use only genuine Crosswater cartridges — others may not align correctly and can void your warranty.

Where to buy the cartridge:

• Visit the official Crosswater Spares Portal
• Search for your valve range (e.g., MPRO, Kai Lever, Wisp, Belgravia).
• Look under “Shower Valve Spares → Cartridges” to find genuine replacements.

Authorised Crosswater retailers also have access to enlarged diagrams that show compatible part numbers. Find your nearest showroom here
