Sap in sewer (5)


I believe the answer is:


This clue is a double definition.

'sap' is the first definition.

'sewer' is the second definition.
(I've seen this before)

'in' acts as a link.

(Other definitions for drain that I've seen before include "Exhaust - pipe" , "Exhaust (of liquid)" , "Discharge pipe" , "Filter" , "Waste pipe" .)
