Help cleaning/changing a thermostatic cartridge (shower mixer tap).
£50
Stepney, Greater London, E1
30th Apr 2026
My shower keeps switching between scalding hot and freezing cold… done a bit of research online, looks like it’s an issue with the Thermostatic Cartridge. Need to remove the cartridge and assess the situation, it might just need a descale. Just not really sure how. I’m guessing it’s not a huge job. If time and skills permit I’d also like to hand a couple of hooks on the wall, just not confident with a drill. Thanks.
