Repairing dripping mixer tap

[Roger465]

A couple of years ago, I fitted one of these from Screwfix. Unfortunately, it drips incessantly (cold side I think).

Is it likely to take some standard sort of cartridge? I know I can take it out and have a look, but I worry there might be all sorts of subtle variations, and I'd buy the wrong one

Thanks

You can replace the cartridge in the tap,various sizes so best removing one and take it to a decent merchant.

I absolutely cannot get the handle off. There is no screw - on the SF site somebody asked the same question, and they said it was tight, but you just pulled.

I've tried pretty hard, with no joy, and am scared of damaging the tap or the sink - any secret plumber's tips for this sort of thing?

Use two levers to alternately force the tap top off, 1/2mm at a time. Protect the chrome surfaces.
Cartridges are quite common 1/2", but the lengths vary so take the previous advice and take one to a decent merchant's.
Replace both cartridges, they're not as expensive as they used to be.
