Betting I received a tap (6)
I believe the answer is:
spigot
'a tap' is the definition.
(I know that tap can be written as spigot)
'betting i received' is the wordplay.
'betting' becomes 'sp'.
'received' becomes 'got' ('get' can be a synonym of 'receive').
'sp'+'i'+'got'='SPIGOT'
(Other definitions for spigot that I've seen before include "Peg for a cask's vent" , "It's a water tap in America" , "Plug for a cask's vent hole" , "Peg that stops the vent of a cask" , "Beer tap" .)
