you didnt give an accurate rant,,Yes Americans, lead has been used for pressure water piping.
And yes, it can withstand pressure required in a water supply system.
Pb. as in plumbing!
This is another one that can stand alongside the American bullshit of the Covid vaccines killing people.
America can't possibly compete with China if this sort of demonstration of ignorance is not stopped!
they are iron and lead combos,,, not just lead,,
No, the cast iron pipe with lead just in the joints are only used for waste water.
Cast iron is neve used for supply lines.
But pure lead was the main choice for cold water supply lines before 1920 or so,
How many homes, built before 1920, are still in use daily as residential property?
Probably about a third of all housing is still using these old lead pipes, and it not only is too expensive to replace them, but there is no reason to, since old lead pipes do not normally add lead to the water. It is only hot water in the home or exceptionally acidic water that causes there to be any elevated lead.
