Hi everyone, getting kind of desperate for help. My hot water suddenly stopped working yesterday without warning, I've tried finding online resources for help regarding this but they're all thermostatic showers whereas my shower is manual.
My current line of thinking is that this is a problem with the shower cartridge (although I'm not sure if that exists in manual showers like this one). I want to remove the hot water "screw" but I'm having trouble with it.
Two questions:
1. How do I remove the black plastic attachment off the shower faucet? It's stopping me from disassembling it. There's also a nut which the plastic attaches to but it's too deep to go in with a monkey wrench or pliers.
2. Is there a cartridge I can remove with this type of shower, and if there is, will it fix the hot water problem?
