ya ya ya..... ok. whatever you say. Were talking cast iron and
aluminum, and steel parts. Same as in a car engine. And as for the other
reply, I PERSONALLY do not have rust and sediment in my automotive cooling
systems. If you do, perhaps you're using an inferior product and not
changing it often enough.

No, it's not BS. The car is an enclosed, constantly mixing system. Lying
in the bottom of the pump in a PW is not; and thus corrosion starts.
Also, the materials for a corrosive reaction aren't present in a radiator
system; they are in a pw.
