Back again to ask ya more silly questions.
The grey waste is 32mm and the trap is 32mm but when tightened the trap slides straight off thus I have a leak here.
In the picture you see I've added a straight coupler but the same result is had when I use the trap. The straight coupler is required as I fell a bit short in reaching the grey waste.
Thinking it was the rubber seal I went and purchased another trap and still the same.
I know it's something I'm doing wrong - but what?
