Signs You Need a New Cartridge
If your mixer tap is dripping from the spout, leaking from under the handle, or the lever has become stiff/difficult to operate, the internal ceramic discs are likely worn or damaged by limescale. Replacing the cartridge is a simple 10-minute fix that restores the tap to "as-new" condition.
Installation Tip: This 38mm cartridge features a hot water limiter (a small blue or red ring). You can adjust this during installation to set a maximum handle rotation, preventing the water from reaching scalding temperatures—ideal for family bathrooms.
