My brand new Katadyn hiker pumped 2.5 gallons (day 2 of 8 day) before the check valve took a crap. I'll never buy another Katadyn product again. I drank stagnant Salamander water
Had a hiker pro. In 2011 I went with a Big Zip and Sawyer inline....couldn't pay me (well you could for the right price ) to go back to pumping water.....dipping and going. I rarely use my sawyer as a gravity during the day. Takes to long. Hate stopping to both gravity filter or pump filter....just dip and go. Pumping is a thing of the past But glad you like yours. I will likely be selling my hiker pro as i haven't used it in over 3 years now.
Luke, couple of questions.
What do you do in freezing temps? During October and later hunts I have to deal with freezing tubes. It is my understanding that freezing the Sawyer filter ruins it.
Do you always have a water sources you can dip fill from? I live and hunt in really arid areas and dip filling isn't an option for a lot of the little seeps I can pump from.
Our filters have no doubt froze a time or two I have no doubt and whether they have been ruined the past few years and I am just relying on my immune system at this point I don't know. Still not sick yet. But on nights I know its gonna freeze I throw them into the dry sack my sleeping pad and quilt/bag were in and stuff them into the bottom of the bag.
As for water sources I found if its deep enough for me to pump from its deep enough for me to use my jet boil or cup or just do what we did around hte 5:00 mark in this video:

Not the perfect solution for everyone but I just dont' see the need to stop to pump water or gravity fill water through out the day. Just drink from the dirty bag and filter as you drink. It has been working will for me for 4 seasons now, but might not be the best option for others.
Any filter (that I know of) will be damaged when it freezes.
