I’ve got TOP - first letters of “ Trouble and Of Pain “
Main = Top

Depends on the wording of the clue, I have seen two versions here.

[dannyk13]

Mainn sources is Tap- initial letters of t(rouble) a(nd) p(ain)

[Toorak]

If there is an ‘of’ before pain then top looks better (definition main)

[shoota]

Mains water is sourced from a tap.

[dannyk13]

Having looked at it again I think Top is probably correct.

[Janetrohear]

Yes there’s “ of “ before pain :

“ Main sources of trouble, and of pain “

[shoota]

Ah...
