Tap & Shower Cartridge Identification Experts in West London
Whether it’s a dripping tap, faulty thermostatic shower, or worn-out valve, the most common cause is a failed cartridge.
However, cartridges are NOT universal – even a small difference in size or spline count can make a replacement unusable.
That’s where we come in.
We help identify:
• Tap cartridges (ceramic & traditional)
• Thermostatic shower cartridges
• Mixer valve internals
• Concealed shower parts
• Bathroom and kitchen tap spares

Steps for Accurate Cartridge Identification
• Check for Brand Markings:
Inspect the shower valve, chrome faceplate, or control handles for any manufacturer names or logos (e.g. Grohe, Gessi, Zucchetti).
• Remove the Cartridge:
Turn off the water supply, remove the handle, and carefully extract the cartridge to reveal its full shape and structure.
• Take Clear Photos:
Photograph the cartridge from multiple angles — especially the spline (teeth on top), the main body, and the base/seating area.
• Key Measurements (mm):
• Total Length: Measure the full length of the cartridge.
• Spline Teeth: Count the number of teeth on the top stem.
• Body Diameter: Measure both the main body and the base.
• O-Rings: Note the size and spacing of any rubber rings.
• Identify Fixing Type:
Check how the cartridge is secured — it may be pushed in and held by a grub screw, secured with a retaining nut, or screwed directly into the valve body.
• Identify Material:
Determine whether the cartridge is made from brass or polymer (plastic).
