Poles apart in pipes too? Wrong! (8)
I believe the answer is:
opposite
'poles apart' is the definition.
(thesaurus)
'pipes too? wrong' is the wordplay.
'wrong' is an anagram indicator.
'pipes'+'too'='pipestoo'
'pipestoo' anagrammed gives 'OPPOSITE'.
'in' acts as a link.
(Other definitions for opposite that I've seen before include "Face to face or directly contrary" , "Directly across from" , "Adverse" , "Oppose it, being faced against" , "antipodean" .)
