The military base/prison at Ft. Leavenworth, Kansas still has parts of

in the 1830s. I'm not sure when the pipe was installed but it was certainly
before the War of Northern Agression (aka the Civil War to less literate of
you). I believe that there are number of cities that still have parts of
their original wooden water pipes in use including London UK.

they called it
"soldering"? The fortunate thing is that virtually all of it is IN the
joint and very little is exposed to the water.

I stand myself corrected. 95% tin, 5% copper.

In the UK, pipes for drinking water now have to
be soldered with
lead-free solder. I am not sure (a) how much a problem leaded solder was
and (b) if the lead-free stuff is actually any safer...
When was the "changeover"?
Parts of my house are a hundred years old, and I'm sure
that I'm not the only one who does not live in a
little box on the hillside made of ticky-tacky.

I can assure you the stuff we have over here is
lead, or at least a
high-lead-containing alloy. It melts at far too low a temperature to be
iron, and it has a density similar to that of lead.
I'm certainly not questioning the existence of lead pipe -
I replaced some in my house with iron pipe.
But it's less common now than it used to be, and I've run
into more than a few extraordinarily ignorant people who
will point to a piece of galvanized pipe and [INCORRECTLY]
call it "lead pipe" (including staff at Home Depot!)
About thirty years ago, Seattle found out that there were
still bamboo pipes in active use!
