Craig, I have had this happen a few times. Luckily it has alwats been before leaving and since I always check before filling. I have descovered that I get 2 years of usable life out of a bladder (HARD USE) and thats about it. My MSR bladders have lasted longer, but fit in less packs. A fix that I use it to trim the hose and ziptie (the narrower the tie the better) it to the nipple. This had made my hoses last longer, but you can only do it once or twice before the hose gets too short. BTW, this works for bite valves too, if you have the new style that slid inside the hose not outside it!
