How to remove this shower valve cartridge?

[User108]

My shower temperature control knob isn't working anymore - only produces hot water. I tried replacing the cartridge but I can't seem to remove the existing one. What's the best way to remove the cartridge I've attached pictures of? It's very very stiff.

Measure distance between the nuts and get new shower rail.

Thanks. Does it have to be the exact same valve/rail as the existing shower unit? I have found one similar online but not sure if there is usually a big risk that they aren't compatible with the shower riser etc.

It won’t be compatible with the existing over / rain head shower rise new shower

I've attached screenshots of my current shower valve.

The valve I am considering buying is product code 17BSV online from Victorian Plumbing. I bought my whole shower from the same website 3 years ago but they have advised me they can't confirm if this valve would definitely work with my existing shower. To me it looks like the connection to the shower riser is slightly different in the attached pictures compared to the product website. Do you think this would be a material difference for it not to work?

Yep different now I’m not saying you might be able to bodge something together etc

If your shower only lasted 3 years why are you buying more rubbish from the same people?

Although this thread seems a bit jumbled? The first post seems to bear no relation to the following ones?

Very jumbled. Not sure WHERE Shaun is seeing an over / rain head shower. All I can see is a valve.

Good old Victorian Plumbing. They sent a customer of mine 2 faulty bidets in a row, then refunded, but this left him with 2 faulty bidets to deal with. Said they wouldn't send a 2nd replacement as they were withdrawing the product from sale, but the website said it was still available for online order. ???

If the OP is going to try a repair, unscrew the cartridge and it's a cheap shower, there may be a suitable replacement for a tenner on ebay, and for that sort of money... Perhaps a Stillson wrench instead of a spanner and try turning clockwise a bit and then anticlockwise a bit more. Back and forth and slowly unscrew. If it wrecks the shower because there's something strange you haven't lost anything, have you?

If you're going to buy a new shower, try something decent like Grohe or Mira. I've never understand how we allowed ourselves to accept a world in which taps and showers should only last 5 or 10 years, however cheap the initial purchase price.

Shaun is saying a new one may not line up with the riser
