    • Thank you for your prompt reply yesterday.
      I will try and descale the cartridge assembly first.
      Could I purchase the four screws please that hold the cartridge assembly into the housing ?, as the heads on some of the existing screws have rusted badly.

      Hello, the cartridge screws only come with the new cartridge.

    • Hi,
      My house was built 10 years ago. It was originally fitted with a Hydramax shower. The end nozzle on the cartridge assemby has threaded so I can,t turn the shower off or on. The shower is installed with the Green cartridge. Will this model 022803 still fit a 10 year old shower unit ? Or alternatively is there a way to replace the end nozzle ?
      Many Thanks

      Hello, unfortunately there is no way to repair the old cartridge, you will need to buy the 022803 green cartridge.

    • hi does this fit a mira hydramax shower

      Mira have never manufactured a Hydramax shower, can you confirm which model you have

    • Hi

      Hi, the Green is specifically for High pressure systems, grey will work on all balanced pressures from Gravity to high pressure

    • Hi

      Hello, they are Torx screws size T-25
