So last night I bought a nano co2 diffuser off ebay. Today I am shopping around for a check valve. I know what to look for, but don't know where to get one. I tried ebay, and anything I can find is overseas. I don't feel like waiting 3 weeks to get a $5 item. Are there any sites within the US that you folks know of where I could find one?
