somewhere

I'm a little stuck... Click here to teach me more about this clue!

'in an unidentified location' is the definition.
I can't judge whether this defines the answer.

'home sewer burst' is the wordplay.
'burst' indicates an anagram.
'home'+'sewer'='homesewer'
'homesewer' is an anagram of 'SOMEWHERE'.

Can you help me to learn more?

(Other definitions for somewhere that I've seen before include "Indefinite or unknown location" , "In an unspecified place" , "location's vague" , "Bernstein classic" , "'. . . . . . . . . Over the Rainbow' (song)" .)

I've seen this clue in The Times.
