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

[Bettyboo]

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

what sort of grips? , i can buy tomorrow but i have some pliers ?? shall i just pull it out gripping threaded part? if i can... .... if i replace the cartridge will it stop the dripping/ water running out (more than dripping now) when i turn on shower !, unless i turn water off , but need on for other people

No that’s the temperature side the left and right ones stop the flow

 

[Bettyboo]

No as that just adjusts the temperature

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

there was nothing wrong with it before!, it only started dripping after Thames Water dug up the road and installed meters ! I was left with two dripping showers ! now this carry on... because Bristan sent wrong instructions and sent me off on wild goose chase " oh you can just clean it taking out cartridge and by soaking in water and vinegar ..." Need a large drink and lie down!

Yep common for them to get grit / other things in your water main when working on it which f ups ball valves and showers

If you look the part numbers of the thermostatic cartridge are the same so bristan just cheaped out and used plastic towards the end of life of the shower as most parts are discontinued

 

[Bettyboo]

as this is very similar do you think I could try a box spanner as in vid ?
i think builder who installed shower must have kept tool to remove the pistons as I don’t have this either
