I used a Hiker pro for years now I have http://cascadedesigns.com/msr/water-treatment-and-hydration/fast-and-light-water-treatment-and-hydration/hyperflow-microfilter/product so far it is working great. Smaller then the Hiker and way faster I also like that it has a back flush. I also like the way the prefilter works.
I have the same pump. I've only had to use it once and ended up really sick. It was a nasty combination of events which saw us with no option than to pump water from what we now call "the funk dam". There were all sorts of nasties floating in that water, so my questions is:
Is there an upper limit to what a filter pump can handle? If water is 100% funk, is there a better option than pumps? Should I pump then add tablets then boil?
I was particularly careful to avoid cross contamination so I can rule that out as a source of failure. Any other ideas?
