Now that I have plenty of time at home, I'm looking at getting back into distilling water again. The question is, do I keep this as-is, or do I figure out a way to add a column on it, and if I do that, do I go electric, and by that point, do I just buy a new system? I was hoping to not put too much money into it either way, I've had several successful runs with this one in the past but it's been several years.
