It's been 100+ out here and I need more water, so I've gone over to the dark side and got a CamelBak. Since I hate hot water, I also got the insulated hose. The problem I'm having right now is removing the old hose. I've pulled and yanked on it, it just won’t budge. I have try running it under hot water, twisting it, nothing seem to move it. Is there a trick to taking these hose off?
