How can you tell? FWIW, I think the ban on lead in plumbing makes a lot

actual contact with the water in a properly sweated joint.

before chlorination or fluoridation, lead from pipe was insignifant as
the lead doesn't dissolve in pH neutral water. Probably get more from the
brass in the hot water fittings and faucets.

However, if the pH is acidic, you have a serious problem. I just had to put
in a $250k pH control system in a tiny (80 customers) water system I run
to raise the pH to slightly alkaline (about 8).
