• blow up the pack with air and curl your shoulders to force the water out, since you can't blow you'll need a pump
Forget asking for help from a friend as jokes such as can you taste my taco dinner from last night are sure to surface even from the nicest people on earth
An air mattress bellow type pump might work. You will need to remove the bite valve each time.
• a worthy option is a dual tube trail running no-suck system

I checked them out in person last week and not only are both the pack and bladder heavier, the 'non-suck' system is just added complexity and cost. There are two hoses, one to drink from and the second hose hanging on the harness to keep the pump is close at hand. Now I didn't bother to see how much effort it took to pump it for the correct amount of pressure, but I thought why would I even need to? Frankly, if its so hard to suck fluid from a hydration tube, I wonder how one has enough energy to breathe. ;)
A breastfeeding pump might work unless you hike with jokesters

Fit great on my Camelbak hose after removing the mouth piece. Impressively did not fall off even with the added water weight in the bulb on it's inaugural nine hour hike. Since water stays in the bulb this would not be good for hot weather. As an added bonus it doubles as a good fifteen foot squirt gun to keep nearby jokesters in check.
