I know msr states it never needs back flushing but during my last cleaning I flushed the hollow fibers with my sawyer syringe same as one would with a gravity system and it was absolutely disgusting how much came out. Took several flushes to stop the dirt coming out
@broswhoknowstuff I was finding I was getting some excess back pressure causing premature failure of the plunger seal. after the flush I had no weeping of the seal and the flow felt like it improved. I use the filter for some pretty silty water but when msr states it never needs a flush seams a bit far fetched after seeing the amount of grime that came out
@@guyswhoknowstuff after removing the hollow fiber cartridge from the pump body I flushed it with a sawyer syringe pushing clean water into the outlet of the filter. I did the msr integrity test after re installing the filter cartridge with no issues

Wow! I'll have to do the same.

@@tgvaillancourt I've got to try it on my old one. What did you use? Did you use a sawyer syringe? Which port did you use to flush: inlet right?
