Wilson asked about an R/O unit. I have one, a Barnstead-Thermolyne R/O
unit. They run $8-15K, and are about $500/year in disposable supplies
to operate. In addition, you get about 1 oz water for every pint of
water that goes through; the rest is waste. So, your water bills go up
to (along with the electricity bills). Since I'm at a university, and
the R/O unit is in my lab, it makes sense. I can't imagine having one
at home; to wasteful and too expensive.

I would think that using a commercial water filter (like at Home Depot)
would clean the tap water more than adequately.
