So much talk of lead in the drinking water in Flint MI these days. Well, I’ve owned 2 homes 
in Flint. I have the same wisdom for those folks as anyone who buys a home built pre-1986.
I recall when I built a home, coincidentally in 1986, that I had to switch from a lead solder to a tin solder. It doesn’t flow the same. But, the point is, per “The Safe Drinking Water Act Amendments of 1986”, homes built before `86 tend to have lead joints so it makes sense to drink & cook with filtered or bottled water. I do.
The law prohibited use of lead solders, pipes, and flux in drinking water systems. Plumbing solder lead content was set at 0.20% maximum. ( previously 50/50 mix w/ tin). It also included wording to require states to enforce the provision.
