Help required with mixer shower.

[Clagsniffer]

As the the thread title suggests I’m having trouble with my mixer shower. The problem being that it won’t turn on! Doesn’t matter if I’ve got the temperature on hot or cold it just won’t turn on. I popped the faceplate off but that’s as far as I’ve gone as I’m stumped at what to do or try. I’ve attached pictures of what I was greeted with as I popped the cover off. Any pointers would be great fully received!

I presume that it worked correctly before, and that the other taps still work correctly now? (Thus ruling out supply issues). If so, most likely problems are either the valve has broken (I.e. you turn the knob but the inner bit that controls the water doesn't turn) or there's a blockage somewhere. 

 

Does the control feel normal when you turn it? I had it with a mixer tap on a bath where the splines on the plastic bit wore down and wouldn't grip the inner bit anymore. It still worked with a pair of mole grips, so I ordered a replacement outer control knob online - there's a website called  'shower doctor' who seem to have all sorts of spare parts, and we're quite helpful at identifying the maker to know which bit to order.

Firstly, I agree about Shower Doctor, very useful site, and very helpful.

Secondly, I'm guessing it's a Triton (or possibly a Mira), and they do have a history

of the flow cartridge 'going off the end' of the controlling thread.

You could confirm that you don't have a blockage/flow problem by shutting off the

water, removing the cartridge, and turning it back on, carefully! It's a lot easier with

2 of you, and don't forget that it goes through the thermostatic cartridge before the

flow cartridge, so you might also have to remove the thermostatic part to check both

hot and cold supplies separately.
