    DD0851D8-397A-48E0-BCFF-5F6DC9720B17.jpeg Hey there,

    I’m trying to replace the thermostatic cartridge on my Trevi CTV shower in en-suite - but it seems completely and utterly seized! I’ve had the adjustable spanner on it and it just won’t budge.
    I’ve attached a couple of pictures - hopefully someone could share a trick or two to get it moving?

    thanks!

    Sometimes there’s a grub screw securing the valve to the body. Have a good look around.

    Is the thread actually the other way?

    Don’t think this is usual.

    Adjustable spanner’s aren’t always the best tool. Which way are you undoing it?

    I personally bought a 24mm deep socket, cost me about £9.00 from amazon did the trick wonderfully.

    Absolutely caked in limescale.

    Try some penetrating oil and maybe a hot hairdryer on it for 10mins.

    Sometimes they come out in bits... Plastic ones usually, so you should be OK with brass.

    I have a huge set of knipex grips that'll handle it!
