Drag Henry round the bend (4)
I believe the answer is:
haul
'drag' is the definition.
(I know that drag can be written as haul)
'henry round the bend' is the wordplay.
'henry' becomes 'hal' (short for Henry).
'round' indicates putting letters inside.
'the bend' becomes 'U' (a U-bend is a kind of bend - pipe under sink).
'hal' enclosing 'u' is 'HAUL'.
(Other definitions for haul that I've seen before include "Tug; swag" , "Quantity taken (by fishermen?)" , "Pull along behind" , "Drag; loot" , "Drag; quantity of fish caught" .)
