Youngsters superior at sorting out pipes? (7)

I believe the answer is:

puppies

I'm a little stuck... Click here to teach me more about this clue!

'youngsters' is the definition.
The answer and definition can be both people as well as being plural nouns.
Perhaps they are linked in a way I don't understand?

'superior at sorting out pipes?' is the wordplay.
'superior at' becomes 'pu' (I am not sure about this - if you are sure you should believe this answer much more).
'sorting out' is an anagram indicator.
'pipes' is an anagram of 'ppies'.
'pu'+'ppies'='PUPPIES'

Can you help me to learn more?
