Hey i foudn 2 Co2 tanks how do i go about checking them to make sure i can use them. No holes or damage to the tank or nozel what do i do next before i take it in to get filled?
they have to be certified every 5 years. they will tell you when you take them to get thim filled if they are expired or not. if so it will cost between 10 and 20 dollars each to certify (hydro-test) them.
