    I have the taps pictured, bought from screwfix a few years ago. The knob circled in red which pulls up to activate the shower head is leaking quite badly. I live in a very hard water area and also the pressure in my flat is quite high. Is there anything that can be done to fix the leaking at all or is it a case of just fitting new taps? Thanks for any advice!

    if you can dismantle them, you can descale the internals and re-assemble with new "O" rings and some silicone grease. it may be that the roughened surface of limescale has worn away the rubber early.

    Some brands, such as Bristan, have a good spare parts section on their website, showing how the mixer is made, and the spares available. Unbranded imports, you're on your own.

    Or it may be less trouble to just fit a new mixer.

    An example

    to me, a worn "O" ring seems the most likely cause.

    With luck, there might be a big nut round the knob that you can unscrew to withdraw it.
