I have a single lever monobloc tap in the bathroom which squeaks/grinds whenever anyone turns the handle.
I've been able to stop the noise using a bit of wd-40 but the squeak has come back after a week of silence. Anyway I suspect that wd-40 and the rubber washer don't go together too well.
What can I do to cure it? Any ideas?
Cheers, Mark, M/cr
