[pct-l] clean water

[Aaron Wallace]

I used a Hyperflow on the JMT.  While at first it lived up to its name and pumped effortlessly, after about a week it became almost impossible to pump water through, even after performing the backflush procedure repeatedly.  In fact, it became so hard to pump through that the rubber one-way valves would occasionally invert--easy enough to fix, but frustrating.  The reviewers at backpackinglight.com found the same issue.  MSR did a recall and issued updated filters, but the improvement was minor at best.
