My understanding is that plumbing solder just has an evil,corrosive but very effective acid flux, while electronic solder has a gentle, non-corrosive but much less effective rosin fluc. The rosin flux protects the molten solder from oxygen but not much else, while the acid flux gives you a decent chance of soldering grungy materials together.

If the joints look good (ie the solder flowed onto the metal) they should be OK. I don't think rosin core solder will do any harm, although the opposite (acid flux for electronics) tends to be really bad news.

Then again, I don't know squat about plumbing so...
