Lead-free solder exists though. It works fine - particularly for plumbing where you don't have tin-whisker concerns. The only problem I've ever had with it is (1) that it turns out Bunnings in Australia sells utterly atrocious flux (the good stuff is also non-toxic, potable compatible and made in USA - and it works perfectly) and (2) that people aren't aware enough of the problem (i.e. my parents house has lead solder all through the plumbing where my father didn't know there was a difference and extended it). EDIT: For any Australians out there - this one - https://www.totaltools.com.au/154135-la-co-56g-soldering-flux-paste-1711882 https://www.totaltools.com.au/154135-la-co-56g-soldering-flu... - buy this one. This is the one which works.
