    Default Stiff shower valve - how to proceed?

    Hi all,

    My customer has a Mira Gem 88 mixer shower. It's 12 years old, and has recently become tight to turn (most likely scaled up). It runs from a combi boiler, and has isolation valves on the pipework.

    How best to proceed? (I'm new to shower repairs).

    I suppose my options are:

    1-Take it apart and soak the cartridge overnight in white vinegar, and see if that frees it up
    2- Replace the cartridge (costs about £90 for the cartridge)
    3- Replace the entire mixer shower (about £181)

    I'd be interested to hear your thoughts,

    Cheers,

    Jennie

    I think it's a plastic cartridge. So impossible to clean.

    I would just replace the cartridge.
