And yet, distilled water tests a 7 with a PH strip, people use copper pipes with distilled water with no major ill effects, and distilled water won't eat it's way through a copper pot either.
You're clearly trolling someone. I guess I'm done wasting my time on you?
Your assertion is that 'pure water' will corrode copper pipe, so it needs to be 'impure' to not do so (using flouride of all things as an example?)
Yet, distilled water - which is as pure water as anyone will ever see outside a lab - doesn't do so to any meaningful extent. And you keep using various clearly inapplicable theory to try to prove a point that is clearly false in the real world.
This has nothing to do with steel wool, after all.
