Help fixing leaking pull-out kitchen mixer tap (seal size?)

[john10001]

Hi everyone,

Trying to fix my mum’s kitchen mixer tap to save her a plumber fee. It’s one of those pull-out spray/shower head styles.

It's leaking right from the bottom of the joystick tap handle lever thingy that you move to turn it on and make it hot or cold.

Does anyone know what size rubber seal/O-ring these typically take, or is it specific to the brand? I have no idea what tap brand it is but I think she got this sink and whole kitchen from B&Q maybe 18 years ago.

Also, any tips on how to actually crack this specific style open without scratching the finish would be great.

Thanks in advance!

Is there a small grub screw at the back of the cap

You'll find that it needs a new cartridge, not an o ring.

+1 - the mixer cartridge in the top has it's own integral seals that are part of it, only option is to replace it.

At these prices, you may prefer a new tap?
