Running water options on craft, type of carrier (8)
I believe the answer is:
handcart
'type of carrier' is the definition.
(something which carries items)
'running water options on craft' is the wordplay.
'running water options' becomes 'H and C' (hot and cold).
'on' is a charade indicator (letters next to each other).
'craft' becomes 'art' (both can mean cunning or trickery).
'handc'+'art'='HANDCART'
(Other definitions for handcart that I've seen before include "Unpowered transporter" , "can be moved around manually" , "unpowered vehicle" , "Barrow pushed by person" .)
