It's best done when the butt is in the dry. Fettle a long-handled
spanner that is a snug fit on the nut and you can keep your head
outside. It has to be a really snug fit so that the nut won't fall out
so perhaps a slot cut into a piece of wood or mole grips taped to a a
stick. I once had to tighten up a nut to stop a tap leaking when it
was accidentaly knocked and loosened by the fencing contractors and
managed to do it with a shortish spanner and a wet arm.

But definitely not a wet spanner and a short arm ....
