Jerry, You are absolutely correct if you are implying I cannot spell, especially since I was on a cell phone and was watching a truck to unload pull in for me to unload , laugh I guess? I can only state the facts told from 2 chemists, distilled water is formed by condensation, it leaves behind any minerals or impurities when evaporated and recaptured, pure water I was told by a science teacher that without contaminants can be somewhat kept from boiling and can be super heated, he said he does this in class and as soon as one grain of salt, rust or mineral is put in it will boil, this I cannot prove nor disprove, I actually don't care. But we tested all waters conductivity in the hospital, be it condensation, potable, boiler etc with a conductivity meter measuring how it conducts electricity, this determined its TDS, or total dissolved solids it did not tell what minerals nor chemicals causing the added conductivity, when its is non conductive or very low it was distilled by some means, same thing goes if the condensate has conductivity there was a leak into it from another source. On forward I happen to be dealing with replacing a hose or something on a car and asked the chemist if I should use distilled water and he said no, two reasons, as soon as its in your cooling system it picks up minerals and electrolysis can still occur, he said use antifreeze because it contains anti-corrosion chemicals to prevent corrosion, make fun or whatever you want, I tested water for 5 years, I saw that distilled water measured 0 on conductivity, and I could add the smallest mineral to it and it raised the conductivity, so yes distilled water in a cooling system can still corrode he told me, it no longer is pure with the rust and impurities from within the system, I did consider him a expert.
Ken you are correct and good point, we did not check high voltage that's not what we where after, we checked the opposite by testing how little it would conduct to see for impurities to see for its corrosive properties, high voltage can jump thru air, so we know it could water...
