Mixer tap problem

[sisterray]

I have a mixer tap on my bath. I pull a knob up (between the taps ) to use the attched shower. lately it has become a bit stiff. So this morning I pulled it up and the knob came off. Small pieces of metal came out of the knob as if a thread has been broken.

Now I cannot pull up the knob with out the help of pliers as there is no purchase. How can I fix it. Can I buy a spare knob or gett a fitting to put inside it

Please help

Thanks

You probably need a whole new tap, but try here in their tap spares section. If they haven't got it, nobody else is likely to.

I've put some wd40 on the mixer valve to see if it become freed up. If this works then it won't be an issue if the knob come off, because the mechanism is working OK

Many tap manufacturers sell diverter valve repair kits for their taps. Bristan is one from whom I've obtained parts before, Ideal/Trevi is another.

If you can identify the brand/model then just phone them up.

If you can't, then post a picture here and someone else might.

Here are a few images


The first shows the tap with the "knob" in the middle in place



The seconds shos the taps with the knob removed



This shows a "close up of the spigot? It's a bit blurry, but it has a hexagon and on top a circular. I'll try an find a way of drawing this/



Finally the inside of the "knob"





One final question , can I descale this without removing it. I was thining of removing the shower attachment and pouring in some descaler through the opening. Would this work ? I live in a very hard water area
