I use soft solder execpt for joining the 1/4" easy flange ring, where I use hard solder I get from my plumber. Not sure on it's % sorry. I really like the bernzomatic solder and flux kit but can't get hold of it any more. I've been using the aquasafe roll from bunnings on this build with 801 liquid flux and it works pretty good but I don't like it as much. It is a lot cheaper though :handgestures-thumbupleft:
