Help! Bristan shower cartridge , cant turn off cold water from shower

[Bettyboo]

Any idea anyone how to remove this inner plate please ?

The one with the bristan logo on ? This doesn’t come out as it’s the body of the shower

The outer plate will come off from the wall normally siliconed on but all you will see is pipes etc

In your very first picture the white spigots / rods either side of the valve these must be the flow controls so my guess is that you’ve not attached/ moved/ not aligned the opac guide that is picture 2905

The cartridge will just pull out might need to twist a bit but have the water off first eg stop tap

As for the controls eg why it’s dripping the left and right brass caps with the two holes in eg holding the valves in that stop the flow

I see thanks , I asked bristan to come out but they said their engineers very booked up .... follow these wrong instructions !
dont know what on earth to do now

 

[Bettyboo]

not sure if a ratchet device would get it out but i think expenisve
but will it stop water flow if i get it out ?

 

[ShaunCorbs]

You won’t do it with a spanner sorry to say you will need grips something you can pinch down on the cartridge and wiggle and pull but the cartridge doesn’t have any effect on the dripping these are the top items either side eg my link ref 1 and 2 these stop it dripping / running from the shower head

No as that just adjusts the temperature

Tbh it looks like you will need to get a new shower fitted
