Are these tanks tested/certified within the last five years?

The one I received was. Anyway, once you go down to get air, they will take this tank and give you one already filled.

how do I get the tank refilled

Hello! Thank you for your email and interest! Most local welding shops will fill them also some major sporting goods stores will. I hope that helps and please let me know if you have any other questions. Thank you! Beverage Elements

is there generally a significant difference in the cost to fill for welding, beverage, and medical grade CO2?

I only use beverage grade exchange. costs $25.00. I don t think there is much difference in price.

In a small town where do you ask if it can be filled and is a 10 half the price of the five to fill? What fill price are you walking away from?

You can get them filled at a welding supply store or try a safety company that fills C02
