Spat out faucets (4)
I believe the answer is:
taps
'faucets' is the definition.
(tap is a kind of faucet)
'spat out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'spat' is an anagram of 'TAPS'.
(Other definitions for taps that I've seen before include "Flow controllers" , "Strikes lightly; eavesdropping devices" , "Military bugle call at dusk" , "Military signal and faucets" , "Knocks lightly on the faucets" .)
