I have a Katahdin water purification system. I had it a couple years before I finally decided to learn how it operated. It's a good thing to try it out, as under stress in a harsh environment, it would be that much harder to operate it correctly. In fact, it's something you should do periodically, I'd think. I use tap water in my test, as not to mess up the filter.
