I want to replace a waterbutt tap on a Sankey standard butt which is about
3ft tall. How can I reach inside the butt to connect the nut ?

In past years I have laid on the grass with the WB horizontal and got in it
that way. Although clean it still stank, and as I am also claustrophobic I
don't want to do this again. Once I surprised myself by stretching my arm
from above down into the WB to apply the nut, but it was very difficult to
do.

Is their some magic gadget to attach to the plastic nut so it can be
connected up with less effort ?

This must be a problem for many people.
