if you live too far from the installer and thinking about doing it yourself. I believe most solders out thre already have a flux core in the middle. And if you just gonna tap the loose solder point I don't think u need to add flux just touch it on the part with less solder so the solder from other part run toward it. There are alot of soldering tips vids on youtube check them out.
