Hmmm... maybe someone hasn't thought through the physics... You're better off having the filter as low as possible (i.e. at the collecting end), to exploit the increased hydrostatic head, thus pushing water through the filter quicker...

With a bit of luck, you can probably fix this by swapping the short and long tubing sections around.

Unless there's something very cunning about the filter that means it works better with a low HH, or breaks if the HH is too high, but that wouldn't give much design margin.

In reply to UKC Gear: I'd also advice purchasing an inline filter alongside a Platypus pack. This gives you double the protection against diseases.

It's amazing how many water purifiers are available, saves you from having to spend a fortune on bottled water.
