Storage facility had a few jars knocked over (5)
I believe the answer is:
depot
'storage facility' is the definition.
'had a few jars knocked over' is the wordplay.
'had a few jars' becomes 'toped' (to tope is to drink alcohol- 'jar' can mean 'beer').
'knocked over' is a reversal indicator.
'toped' reversed gives 'DEPOT'.
(Other definitions for depot that I've seen before include "Bus station in the US" , "Storehouse or warehouse" , "Storehouse or terminus" , "Bus station or warehouse" , "Toped (anag.)" .)
