Saloon spout (3)
I believe the answer is:
tap
'saloon spout' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tap that I've seen before include "Light stroke" , "Get money from, strike" , "One can be hot or cold?" , "Light touch (hot or cold?)" , "Bugging device" .)
