One getting up to find pipe (5)
I believe the answer is:
riser
I believe this is a double definition.
'one getting up' is the first definition.
(one rising or getting up)
'pipe' is the second definition.
(I know that riser is a type of pipe)
'to find' acts as a link.
(Other definitions for riser that I've seen before include "Vertical upward pipe" , "One on the way up" , "Front of a step; vertical pipe" , "Upright piece in stairs" , "person advancing position?" .)
