Discuss How to remove this tap cartridge? in the UK Plumbing Forum | Plumbing Advice area at PlumbersForums.net
Thanks Shaun - just had a go. Doesn’t seem to want to budge (I admit I’m not hammer too hard in case it does need to unscrew). Not seen a tap like this before - it’s a Bonade (German) if that is any use/clue!Have you tried a flat screwdriver with a hammer in the holes to shock it eg undo
