I have a Badlands Ultra Day pack I picked up this year and love it. I added a hydration bladder to it, also a Badlands. The plasitc taste of the water is horrible! I've used other before and don't remember of the taste being so strong. Any tricks? I've rinsed with hot water, ran 4-5 full bags of water through thinking maybe it was the water hose still the taste remains. Thanx for any input.
