If I were you I would investigate a reverse osmosis system for your home from a local vendor that installs on demand RO systems for drinking water. You could have a tap installed straight off the unit so the water is not traveling through household plumbing. I know that lab grade RO systems provide water that is much, much, better than any water that can be produced by distillation. I assume the home units are pretty good too. Purified water, once its dechlorinated, can go septic pretty quickly, so you want a system that produces it as you need it.
Finding ultra-pure water locally...
I've been reading up on record cleaning, and there seems to be something of a consensus that rinsing with ultra pure water / lab-grade water / triple distilled water (I'm assuming these are just different names for essentially the same thing?) helps. Where does one buy such water locally? I would imagine paying postage to ship 10 lbs of water would be rather high. I'm in the San Francisco Bay Area. Tks!
