How to change this?

[Kentcounty]

Can anyone help me fix my leaking shower.
I'm guessing I have to change the cartridge but when I take off the flow knob this is all I see. There's no bolt, just the threaded section for retaining the facia plate. I was expecting to see a nut of some sort. Is there a special tool to remove it or am I going about it the wrong way? I think it's a Victoria plum shower.
Thanks in advance!

Firstly, take the fascia plate off. You will be able to see if there are any more retaining grub screws.

The cartridge should just pull out, it is held in place by a series of rubber o-rings along the shaft.

Contact showerdoctor.com, send them a pic. Quite often if you buy the new valve from them, they also supply instructions.

Pulled it apart a little more. Still unclear.
Let's hope shower doctor knows!

It could be a peg spanner you need......the sort of thing that tightens the arbor nut on an angle grinder?

Have you tried to pull it out?

Shower valves don't just "pull out".

Shower valves don't just "pull out".

If the 'cartridge' is a pull out type, once any retaining nut has been removed you will be able to just "pull it out".

I am not talking about the valve itself, I assumed that much was obvious.

The retaining nut is what the OP can't undo. I assumed that was obvious.

As BM said, you need a peg spanner, or some very good pump pliers to purchase on the outside edge.

Mind you if it is Victoria Plumb crap, he's probably screwed for parts anyway.

Good point!
