So I made a gravity filter using the sawyer inline filter purchased from REI. At first the system worked great, pumping out about a liter a minute as advertised. After about 20 L however the pump just died… It showed no signs of slowing and was going strong and then all of a sudden reduced from a steady flow one attempt to a trickle the next… I took it back home from the trip confused and figured backwashing would solve the problem, but even after backwashing several times with their supplied adapter the filter still will barely drip. Anybody else experience this or have any ideas on what is wrong?
