Leaking basin tap

[markwm]

I have this basin mixer tap from Q&B: http://www.diy.com/diy/jsp/bq/nav.j...refview=search&ts=1271623995747&isSearch=true

Keep noticing pools of water on the top of the basin. The leak is coming from the rim at the top of the tap just under the lever. I don't see anyway of getting inside there to see what's going in.

Is it knackered?

that will be a allen grub screw.
unscrew the lever on the front check in the bottom of the hole.

you'll need a small allen key.

it'll be the cartridge leaking anyway.

I removed the handle, tightened the grub screw inside as tight as I possibly could and it's still leaking.

Also, tried removing the grub screw to see if the top of the tap would come off but it won't. I've now tightened up the grub screw so much that I can't undo it.

Oooohh, you've gone and done it now, call a plumber and see if hes up for a challenge.

What exactly is the grub screw supposed to tighten/untighten?

the grub screw should hold the handle on the cartridge.
