I have a Pure Energy 72ci 3000psi steel tank that has been sitting in my closet for at least five or six years. The reg reads that it has ~2500 psi in it. The hydro test date is 04/2009, so I'm well past that. Should I be worried about this? I've read that regs get stressed by long term storage with air in them, so if I go to drain the air out of it am I looking at a safety hazard?
It hasn't been used all that much, never took any hard hits, no dings or anything just some cosmetic scratches.
