Thanks for looking. When the tap is swivelled the collar doesn't move, so yes you're correct in that the two parts don't move together. However, the threaded shaft beneath the collar (ie under the worktop) moves with the flexi pipes and body of the tap. All very odd. Can't be good for the pipes.
Hi, I have just fitted the above tap into a new sink, but there appears to be one major flaw.
The body of the tap moves with the connections beneath when the tap is swivelled. This means that the flexible hoses beneath the tap also twist, putting them under extra strain.
This seems highly...
