This question is regarding Mira 415/415B Cartridge Assembly (Black/Red) - 902.55

Recessed Mira 415 shower

I have a combi boiler feeding our Mira recessed 415 (Manuel temperature adjustment) it has the red override press button. For a few months now water drips from the shower head. However now no matter how tight we turn it to switch off it leaks quite a big drip! I’m quite could at DIY so do you think it is within a reasonable DIYER to change the Mira combo force 415 cartridge 902.55 and does it come with all the seals I will need. Thanks for your help.

Yes changing the cartridge is fairly straight forward.

Turn off the water and take plenty of photos as you dissemble and remember the order and orientation of the parts as you take them apart.
