Problem badly affected taps (5)
I believe the answer is:
hitch
'problem' is the definition.
(I've seen this before)
'badly affected taps' is the wordplay.
'badly affected' becomes 'hit' (I've seen this before).
'taps' becomes 'ch' (I've seen this in other clues).
'hit'+'ch'='HITCH'
(Other definitions for hitch that I've seen before include "Jerk" , "something uplifting" , "couple" , "Temporary problem" , "Make fast" .)
