On my day-hike last Saturday, I went to get more water only to find out I can't get water to flow through my Sawyer Squeeze filter....Luckily I had my stove, so i ended up boiling my water. I vaguely remember using my filter last November, and I vaguely remember back flushing it after the trip. I haven't used it since... If I even used it last November? I might have used my friend's filter during that trip, maybe?

When I got home I tried back flushing and it wouldn't flow water backward... I'm guessing something grew inside of it and stop all flow? Anyone else ever had this issue? I soaked the filter in warm water for little while, and it doesn't seem to have any impact..

Edit: Never mind, I found a trick to try on their website. FAQ
