Wet spray plus short, weird thing needed for firefighting (5,6)

I believe the answer is:

water supply

'thing needed for firefighting' is the definition.
(eg to supply firefighters' hoses)

'wet spray plus short weird' is the wordplay.
'short' means to remove the last letter.
'weird' indicates anagramming the letters.
'wet'+'spray'+'plus'='wetsprayplus'
'wetsprayplus' with its last letter taken off is 'wetsprayplu'.
'wetsprayplu' with letters rearranged gives 'WATER-SUPPLY'.

I've seen this clue in The Times.
