We bought a Mondella Resonance curved sink mixer from the local Bunning store recently and have it successfully installed. It is working ok. The information on the box suggests that it uses a 35 mm Cartridge.
Yet we have not been able to find information on whether the cartridge could be replaced, or how that can be done. That model differs from older models in that access to the allen key screw is not obvious, although an allen key has been included in the package.
Also the type of replacement cartridge is not specified.
We would like to have this information as our experiences indicate that all taps leak after about 5 years of working.
