Summary - water qualty report required for new waterjet makes me wonder "Is the hassle of getting RO water from the grocery store to use in mixing coolant actually worthwhile???"
The coolant in my shop does not stink. It works fine. I change it out very rarely (think years) though I don't run anywhere near as many hours as most of you do. This is all goodness so of course "what's the problem Bryan???"
Since I got my first enclosed VMC and started using coolant, I've always used Hangsterfer's S-500CF, which I've always mixed with water from the grocery store pure water machine. (By hauling 8 or 12 or so 5-gallon carboys back and forth.) This is a hassle but always worked.
These machines have a label that goes on at great length about how wonderful they are, but the gist is:
charcoal, UV-light, some more filtering, RO, some more filtering, UV-light, etc.
In other words, filters, UV, RO.
Recently, I had the tap water tested as requested by a waterjet vendor, for a new waterjet that is coming. And as I read the report the water is VERY soft and has zilch wrong with it. (Though they don't test for bacteria.) Various public sources suggest the tap water is also very low in bacteria. (This is from the Seattle Metro water supply used by basically all of the city water supplies in West King County.)
Soooo......
Should I just mix the coolant with water from the tap? What are RO and UV treatment actually getting me? (I've not had the grocery store machine water tested, for all I know it's no better.)
Thoughts? Experience? Any members in the Seattle area actually tried it?
