'large volumes of water?' is the definition.
I can't judge whether this definition defines the answer.

'should inventor rent something to hold' is the wordplay.
'to hold' indicates a hidden word (I've seen 'holding' mean this).
'TORRENTS' is hidden within 'should inventor rent something'.

Can you help me to learn more?

(Other definitions for torrents that I've seen before include "Cats and dogs" , "Foaming streams" , "Downpours, cloudbursts" , "Fast streams of liquid" , "Rushing streams or violent flows" .)
