But the Barenaked Ladies said "if you blame it on the rain what can be gained so, if all else fails you can blame it on?.. [Sawyer's water treatment system]".
Yes that is right, Sawyer. Had it not been for the pure awesomeness of a similar style gravity filter system by Sawyer, I would blame my Platypus water treatment system's difficulty purely on the rain. Why?
An exceptionally rainy year this past field season (I guide research expeditions in Mongolia) deposited a lot of silt into the rivers/streams in the remote valley of Mongolia where we were working. Although it was nice having a wealth of water for bathing (something we had not enjoyed in the past), the overload of fine silty sediment really clogged my Platypus system, resulting in daily cleanings by the end of the project.
(As a side note the system is easy to clean via back flushing, but does waste time and water).
I was more than willing to excuse the poor performance to the overload of silt; however, a member of the research team was the proud owner of a Sawyer water treatment system? a system that never once had any difficulty or reduction in flow capacity. Their system filtered water just as fast on day 30 as it had on day 1. Weight or filter life be damned, next time around I recommend a Sawyer.
