How can you tell? FWIW, I think the ban on lead in plumbing makes a lot
of sense. Still, I'd think that there is very little--if any--lead in
actual contact with the water in a properly sweated joint.

Nor does the lead dissolve in water - lead pipes were in use for hundreds
of years. Of course it may depend on the type of water. Hard water coats
the insides of the pipes.

Look up lead solubility in water and you will find some interesting
papers. The type of chlorination has a big effect on the solubility
of lead. There are other factors about what is in the pipes and
water. Your best hope is that the scale stays Pb++ and that the lead
get covered.

Lead from the pipes showed up as a problem for the Romans.
