I just got all the equipment to begin kegging. I've got the fridge, lines, dual manifold, all that good stuff. I sized out the freezer, and was able to fit a 15lb C02 tank in there, but I wasn't positive I could fit a 20lb C02 tank inside. Well, no problem, I can exchange or fill it anywhere. Well not so much. Most places I call have never heard of a 15lb C02 tank, and those that have heard of it never sell them, so they only have 10 or 20lbs. I've been looking in the Redmond WA area, and the only place that even fills C02 tanks is http://www.centralwelding.com/Lynnwood.htm Am I doomed to live a life of filling at this one station, or is there another solution that I'm not thinking of? I tried calling what little paintball stores I could find, surplus stores, beverage stores, all the welding stores in the area. Any ideas?
