Please can you help. I’m trying to replace the cartridge on our monobloc kitchen mixer tap. I’ve found the secret hexnut and removed the handle cover, but can’t get the shroud ring to budge. So far I’ve tried lots of WD40, descaler (vinegar, lemon juice, oust) & boiling water. Unfortunately it’s on the side so difficult to fully soak it. My pump pliers fit, but won’t grip it so I bought a belt wrench, but this also slips off. There’s no flat edge to grip! Any ideas- should I try hitting it gently with a hammer to try to free it or would this do more harm than good? We live in a very hard water area so I think it’s welded solid with limescale where it’s been leaking for ages (although I’m also starting to wonder if the threads are crossed).
I saw on another similar thread, someone suggested drilling a hole but there’s only about 3mm from the edge to the inner brass nut so I can’t quite picture how this would work- I think I might end up drilling the two pieces together.
