What essential is the difference between distilled and deionized water? We are building a new high school and we have the option of one of the other with plumbing to each room. Does anyone have experience with this situation?


So far as quality goes, distilled is better than deionized. However, having had extensive experience with both, I suggest you simply purchase distilled water from a reputable supplier. The costs and aggravations associated with maintaining deionizers and stills is considerable. Unless you have funds to hire a maintenance technician, you will be spending a lot of your time looking after whichever system you select.
