It should be working like the manual said. Most times the valve is still sealed when those mouthpieces are shipped. Your not supposed to cut into it since this is the most critical part of your whole hydration system. The Camelbak Valve is known to be one of the best in the marked. It stays closed until you bite onto it, meaning that there can neither get Air into the tube (very unconfortable) nor getting water out of the tube unintended.
Opening the sealed valve for the first time should be fine with just a little preasure between your fingers and rolling the valve...
Give it a try! /ubbthreads/images/graemlins/grin.gif
