deionized water versus distilled water
I was watching a TV show about a family living off the grid in Australia. They had a solar system for generating electricity. The fellow made a point of saying that they had to use deionized wat...

I just checked the conductivity (micromhos) of all the water around my house. I've used the storefront water machine stuff in my bipap for years w/o any scaling and it still measures 30. Sparklett drinking water is 40. I have an old bottle of store bought distilled and it's 17. The store front machines claim it's distilled and RO'd but I never believed it. The machines would have to be several times larger to put out the gallons they do. My lousy salty raw water at the house, from nearby wells is 3700. My softened tap water is 4000. I use water from a simple two-tank non-recirculating DI system at work to keep my water test equipment rinsed out and it won't move the needle on the conductivity meter and that's really only entry level DI.
One time distilled water is not pure. WFI water (water for injectibles) is 8 times distilled. Each time strips off more organics.
Completely DI'd water is hard to keep DI'd. It will instantly start reionizing even from air exposure. My old bottle of distilled water was probably less than 17 when it was new. I use the store bought distilled water in my batteries and radiators. I've never seen DI bottled water in stores but I'll start looking. Craig
