Where to keep the hose readily available (2,3)
I believe the answer is:
on tap
'readily available' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for on tap that I've seen before include "Where to find a washer" , "Available whenever needed" , "Where you may see H or C" , "Constantly available like beer from keg" , "Readily available" .)
