Dead tanks are handy to have in the shop for rigging back plates etc.Yes it does. I need to read more about hydro testing. I hate not being able to talk "the talk" and know what I'm talking about. I will print out the PST D100 to take with me and make sure that's what they did. I also don't want to be a pain in the butt if they did it correctly by not knowing what I'm talking about.
