Replace Your Hydration System Hose




Unless you are very, very, very disciplined in washing and drying your hydration system hose, or unless you keep it in the freezer (which gives it a bad taste), green or brown stuff will eventualy start to grow in there.

Instead of throwing away the whole thing or buying an expensive replacement hose, you can replace the hose with a cheap tube found in any hardware sotre.

Step 1: Materials Needed

You'll need the following:
- your hydration system
- utility knife
- replacement hose - vinyl tubing
- optional: any replacement part for your system

The replacement part will help you buy the tubing at your local hardware store. You be able to try different inner diameters. I tried many at the store and chose the tubing that was big enough to let the piece in but not out (that was 5/16 of an inche in my case - I have the Source system available at MEC). I recommend this approach if you don't want the new hose to leak. The tubing is typically found in the plumbing departement.

If you do not have any replacement part, you can go buy the tubing after the next step.

Step 2: Remove the Old Hose

The step title says everything... some tubes will easily pop when you pull, some will require you to cut them with the knife, as shown in the picture.

Step 3: Put New Hose

Plug in the tubing. If the tube fits too tightly on the pieces, you may need to lubricate the parts. I would recommend vegetal oil (in any case, something edible and not too tasty...).

You're done!

    the army sends these out for free, i mean the whole hydration pack and backpack, however if you have one of the expensive one this is good. Could you flush the old one with alcohol or bleach or something to kill the stuff?

    I haven't tried that. I typically wash the bladder and hose with a bleach type of liquid, but made for hydration system (so it does not leave a bleach taste). After some time, the stuff gets too strong. My guess is, the best way to clean it would be with a thin and long brush, to scrub the inside (they're sometimes sold where you buy hydration systems, but they're expensive).

    Great idea! However, if you think the hose is still salvagable try this... Works great! :)

    try dipping the new hose in very hot water then slide it on instead of the oil

    If this sounds really stupid it might be because I don't know what a hydration system is. It would appear to be something you drink out of. If that is the casei, I would use hydrogen peroxide to flush the system. It kills bacteria and bleaches without leaving any taste.

    You've guessed right! The hydration system basically is a bladder with a hose that you put in a backpack (some are made just for this, well knows brands include CamelBak and Hydrapak) in order to drink during doing outdoor sports like mountain bike or trail running. It did not come to my mind to use hydrogen peroxide, nice idea, I'll try that in the future. Thanks!
