Bath tap cartridge stuck ?? pictures

Hi all,

This post follows on from my previous one regarding removal of a bath tap. It has now been pointed out to me that it is only the top knurled part of the cartridge that has sheared off and that if the cartridge was replaced then everything will be ok.

Unfortuantely, I cannot unscrew the existing cartridge, despite soaking the inside of the tap with WD40 for 2 days. When I try to unscrew the cartridge the entire tap rotates and I am concerned that this will damage the pipework feeding the tap.

I have attached a couple of photos, is there anything else to undo before trying to unscrew the cartridge?

Many thanks for your thoughts on this.

I'll have another go at it and hope that the the feed pipe doesn't spring a leak!


Damn it, the top of the cartridge has just rounded off with my last effort. The box spanner bit just spins round now.

Oh well, I suppose there's nothing else I can do other than replacing the whole tap.

As a last resort, remove the tap (so you don't damage pipework/sink) Find a socket that is slightly smaller than the nut, if the nut is imperial you may find a metric that is slightly smaller and vice versa. Try hammering the socket on to the nut and then use it to remove nut. Its a bit brutish but perhaps worth a go as you've nothing to loose.
I think you may be wasting your time. Even if you do eventually manage to get the cartridge out, unless you know the manufacturer you will then have to search to find a suitable replacement cartridge. This may well be a long-winded task in itself.

Because the component sheared off, I'm guessing it may well be a low quality Chinese made tap. I'd be looking to replace with a better quality branded pair.
Yes your best bet is to change the tap altogether, when you get the new one take it apart and put it back together with a bit of WRAS approved silicone grease on the thread, to hopefully make seizures a lesser occurance. Its what i like to do and purely a suggestion.

Hope you get it sorted.
Thanks a lot for all your replies. I've got a couple of names of quality taps. Will buy some and might have to post another question when I attempt to plumb it in.

Thanks again.
