I don't know where this fellow shops, but as far as I know, plumbers ALWAYS
use acid fluxes.  These include liquids or pastes with zinc chloride as the
active component- it yields hydrochloric acid.

I have NEVER seen rosin flux in plumbing stores.  If you use acid flux on
your electronic circuits, you can kiss them goodbye.
