Also, I think Brew Your Own Beer in North Scottsdale will refill. But I highly urge you to go else where. I was in there a few years ago and the owner/guy in there treated me as if I didn't know how to loosen or tighten korny kegs valves on a unit I bought from them same day. The treads were cross threaded from the factory and I couldn't get it off. Ended up breaking the 2 gallon keg. I was treated as if it was my fault. The guy ended up calling the owner and it went south. I refuse to give them any of my business. So, I found Brewers Connections in Tempe and I love them!
