When I first got it I was lifting it up and pouring 30ltr barrels in it to fill! Bloody nightmare! If thats the way you operate then it IS a pain!
I opertate the backpack like this
Dave I'm refilling from barrels and I totally agree its driving me nuts, but even if its not just for refilling, carrying the backpack for me is still a pain, personally I'm fed up with carrying more water than is needed, I have no dought wfp can do the job but if things dont get better than using a backpack I'll go back to ladders. personally I think I'd rather have had a freedom trolley or I may even make a trolley out of the backpack.
