Best water for cooling system mix

[Tourist]

Nothing scientific and don't intend to start a debate. Just some food for thought and we each make our different choice and I would not casually dismiss the value of minerals in water, even in a developed country.

1. If God ever intended human to live a healthy life, I am sure he would have created some water on earth that is de-mineralized to start off with. And there are none.

2. Search google "people live longest in water with high mineral content" and you ended up lots of links on this issue. I just randomly picked one

And here is a report from University of Arizona and I presume it's talking about a advanced country like the USA and hard water contains higher level of minerals.

"Yet hard water has it benefits. People who drink hard water are less prone to heart disease. Hard water also seems to help develop stronger teeth and bones."

Heavy Water works best but it is so hard to come by! You just wait now that I have let the cat out of the bag everyone in Nascar will be running Heavy Water in their radiator.

Reverse Osmosis causing health problems? I do not know why most of us in the US would need more minerals.

Since when does Nascar use nuclear reactors for powerplants?

Last I heard, they are still using carburetors

.

Just the water not the whole reactor! Oh and lets not forget do not drink Heavy Water it is lethal to humans!

it wasn't God's plan to put cryptosporidia and other bacteria in the water like typhoid. then there's radon and arsenic both occurring naturally in groundwater but carcinogenic to humans.

I drink 32oz of RO water at work plus more at home on a daily basis along with a regular US diet since March. Just had my blood checked recently and mentioned the usage to my doctor. No issues and no concerns from the doc.

As far as price. I don't recall where I saw it but factoring in the life of the filters the cost of RO water was estimated at $.36 per gallon.
If I crunch the numbers for my personal useage, I'd bet it's much cheaper.
A filter twin pack is about $30 and 2 are required per change. Estimated life is 6 months, 750 gallons, IIRC.
RO Membrane is about $30 with an estimated life of 5 years, ? gallons.
I'd have to see what I'm paying for my tap water, but my system consumes 7 or 8 gallons to produce 1 gallon of RO water.
Anyway, it's far cheaper than the drinking water bottles my wife was buying...

It would be nice to have a source at home for the convenience of making as much water as needed whenever you need it without having to jump into your car to get it...

I was under the impression that de-ionized water is fairly corrosive.

Water, by nature, is the universal solvent. It picks up at least traces of most everything it comes in contact with. The higher the purity, the more aggressive it is. Even in its purest state it is a far cry from hydrochloric or sulphuric acid.

It takes very little for it to lose its aggressiveness. By the time it gets mixed 50/50 with coolant its not any more aggressive than tap water mixed with coolant.
