Shower cartridge not budging

[James0111111]

Hi folks,

The cartridge on my shower tap has seized up after about 10 years of use. So the plan is to fit a new one. However, the old one simply is not budging. I sprayed on some WD-40 but it won't twist at all (attached pic).

I read you shouldn't force it by twisting too hard. Is this true or do I simply apply more elbow grease with my spanner?

Any pointers will be most helpful. Thanks all.

James

Some of them have a grub screw (usually 2.0, 2.5 or 3.0 mm Allen key) in the underside of the body to keep the cartridge from unscrewing. Use a small mirror like a dental mirror, and a torch, to see if that is the case. If you know the make and model, look up a spares exploded diagram.

Try it tomorrow morning....................after you have had 3 shredded wheat.

Or ask a teenage boy, they normally have a good grip.

Do you mean the control valve or the thermostatic cartridge?

Thanks guys...sorry I mean the control valve (top valve in the pic) which controls the flow/on/off of the shower.

There aren't any grub screws holding it in place. And may have to try the shredded wheat at this rate! Ha.

Thermostatic cartridge, but could be either / both.
