Tank rehydro testing
Hey quick q: is a tank still good when its 5 years past its hydro test? I'm buying a used hpa steel tank supposedly used last year, but date on tank says it needed to be hydro 2008. Will it still be a usable tank? Does the age of the tank affect performance? will it pass the hydro test? Is there an eye test I can do to see if the tank can pass?
I know steel has a 25 year life with 3-5 years hydro right?
