Cherished getting nonsense on tap (7)

Ross

I believe the answer is:

petcock

'tap' is the definition.
(thesaurus)

'cherished getting nonsense' is the wordplay.
'cherished' becomes 'pet' (as in a pet project).
'getting' means one lot of letters go next to another.
'nonsense' becomes 'cock' (I've seen this in other clues).
'pet'+'cock'='PETCOCK'

'on' acts as a link.

I've seen this clue in The Guardian.
