Pressurized Hydration Pack
Intro: Pressurized Hydration Pack
The parts for the project are listed below and it is important to be careful when using the bike pump as it is discharging carbon dioxide.
I use the pack to clean things off when there is no hose available or when I'm just in the woods.
Materials:
1.Swiss gear hydration pack
2.In line pressure regulator
3. Co2 bike pump and Co2 canister refills
4.Thin piece of wood
5.Air Blow gun attatcments
6.Drink nozzle/spigot
7.3/8” compression fitting
8.3/8” quick connect tubing fitting with female threads
9.3/8” polyethylene tubing
10.3/8” clear tubing
11. 3/8” check valve
12.¼” hose barbs (2)
13.Small Hose clamps (3-4)
14.Waterproof/ airtight sealant
Tools:
•Drill and drill bits
•Electrical tape
• Thread seal tape
•Knife
•Adjustable wrench
• Flat Screwdriver
STEP 1: Drill Hole and Mount Compression Fitting
Take your drill and drill a hole that is slightly smaller than the threads on the compression fitting.
Wrap the compression threads with sealant tape and screw it into the cap for the hydration pack. It should be very tight and have resistance when turning the fitting but make sure not to over tigthen the fitting though or it will strip the cap.
When it seems tight enough take your water/air proof sealant and seal all around the fitting both in and outside the cap make sure that everything is covered as even the slightest leak will compromise the project.
STEP 2: Connect Tubing to Check Valve
Take the clear 3/8" tubing and cut it to about 1.5 feet and slide one end over the left side of the check valve.
The check valve is holding the air in the chamber and it also is keeping the liquid from seeping down into the pump.
STEP 3: Adding the Pressure Regulator
Screw the 1/4" hose barbs into both sides of the presure regulator and then slide the second end of the clear tubing from step 2 to the right side of the pressure regulator.
Add a hose clamp to make the connection airtight.
STEP 4: Connect Pump to System
Take the other end of the tubing conected to the pump and connect it to the left side of the pressure regulator, use a hose clamp to secure the connection.
STEP 5: Attach Nozzle/spigot to Drinking Tube
Add tape around the connection so it does not cut you.
STEP 6: Finish
Put the hydration pack in the backpack and feed the drinking and pump tubes through the designated slots on the back pack.
I added a cable tie to the pump tube to keep it secure.
Fill the hydration pack with anything you want and screw the cap on tight, connect the tubing together and zip up the back pack.
Squeeze the trigger on the pump and it should fill up the pack, pressurizing it. This pressure will force the liquid out the drinking tube when the spigot is opened.
Remember to regulate the pressure with the pressure regulator so the hydration chmamber does not burst.

I would use a little ball pump myself.
Also, the co2 in those cartridges is not food-safe!
