You men that weld or have any pressurized tanks. Where do you get them hydrostatic tested locally? A few friends are flying in over the weekend and we plan on exploring mines. One of the mines is an underwater salt mine in Lake Mead. Problem is, he lives too far from a place that can test tanks, so we'll just do that here if the tanks are beat up. They're probably fine. I've had accidents with old steel, but never with aluminum.
