How is that different from the metal pipes through which drinking water goes through to reach your kitchen tap, some of which are over 100 years old if you live in the UK? The contact with metal shouldn't be the problem in itself. Legionnaires disease either, the water from the river isn't drinking water to start with and the water out of the datacenter wouldn't be drinking water either.

When you start of with 'a stupid question' and people then give you lots of reasonable answers and you persist with more such questions at some point you cause me to doubt if you were really asking your first question in good faith.

I apologize for not humbly submitting to the first comment on HN. If I gave the impression that you were not the ultimate authority on this topic, I certainly did not intend to do so. I should know better than to oppose common sense on a topic that is way over my head.
