Duno about that, copper is poisonous and tastes like crap.

Huh?

You mean the MILLIONS of feet of copper water pipe in this country are poisionous?

It's ONLY a problem when heated, with certain acidic foods - which is why you tin copper pots

Yes, you can't cook acidic foods like tomatos for long in a copper vessel. But I think for normal hot & cold running household water copper is probably fine.

I think it's more of the lead from the solder used it join the copper pipes.
