This is an instructable for a presurized hydration pack. There is a co2 bike pump which pressurizes the hydration pack storing the liquid and the pressure inside the pack forces the liquid out of the hose giving it a spraying effect.

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.


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



  Drill and drill bits

  Electrical tape

  Thread seal tape


  Adjustable wrench

  Flat Screwdriver







Step 1: Drill hole and mount compression fitting

Screw the quick connect tubing fitting onto one end of the right angle compresion fitting; tighten fully.

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.
Nice idea, although it looks a bit over complex for what you are trying to do. <br> <br>I would use a little ball pump myself. <br> <br>Also, the co2 in those cartridges is not food-safe!
Listen to ilpug. That CO2 is not safe you may get unwanted contaminants in your water.
switch to whipit cartridges, made for those whipped cream making gidgets.
Yeah, you should do that, but they don't fit well into the c02 filler. maybe you could make a spacer so it would fit?
Couldn't you just blow air into the drinking tube for the same result?
Jet pack?
Don't fall back first on the road on your speed bike going 60mph...?
Private videos? or just me?
should work now
I too got this video is private.
