Very little pressure to turn on the waterworks (4)

Ross

I believe the answer is:

weep

'turn on the waterworks' is the definition.
(I've seen this before)

'very little pressure' is the wordplay.
'very little' becomes 'wee'.
'pressure' becomes 'p' (abbreviation).
'wee'+'p'='WEEP'

'to' is the link.

(Other definitions for weep that I've seen before include "Express grief or sorrow" , "Turn on the waterworks" , "leak" , "Bawl" , "Display sorrow" .)

I've seen this clue in The Times.
