Discussed gardening tools for water distributor (4)
I believe the answer is:
hose
'water distributor' is the definition.
'discussed gardening tools' is the wordplay.
'discussed' indicates a 'sounds like' (homophone) clue.
'gardening tools' becomes 'hoes' (I've seen this before).
'hoes' is a homophone of 'HOSE'.
'for' is the link.
(Other definitions for hose that I've seen before include "Stockings; drench" , "footwear" , "Stockings, etc." , "Socks and stockings" , "plumbing connection" .)
