    Hi Everyone,

    I have a dripping show, so I need to disassemble my thermostatic shower mixer bar. The water flow valve is made by the company Grohe. The valve has a small slot (see red arrow on first photo). If I insert a screw driver the valve lifts slightly from the mixer unit, but this seems not to be the only fixing mechanism as the valve still does not come away from the mixer bar.

    I would be really appreciative of any help on this!

    Many thanks,

    David.

    Could be stuck from limescale David, suggest you try a little harder or try the showerdoctor.com (be prepared for a two day delay in response though).

    Aw, thanks very much rpm. The cartridge is pretty stuck so I really think there must be some other fixing mechanism. I'lll wait a day or two to see if anyone else can help me. Otherwise - I'll try your recommendation - I guess you mean showerdoc.com ??

    Hi David,
    As you have a bar shower valve with (150mm pipe ctrs) it might be more cost effective to replace with a brand spanking one rather than changing cartridge as Mira & similar have a 5yr warranty.
    Just a thought,
    Good luck ,
