Please Sir…

…it just came off in my hand.
Some years ago I was given a Kilner© "Drinks dispenser" for use in Kombucha brewing.  
To be politically correct - do I HAVE to say "Other makes are available."?
;¬)
I finally/recently graduated from a daily brew to the continuous brew system. 
Yesterday this happened. Plan A - attempt a repair; as the body of the tap is hollow I have an idea .  It beats having no eye deer? We shall see.
