I agree with Peppie. I couldn't imagine dragging a huge tank outside to test it for leaks. 9 times out of 10 the leaks are at the bulkheads which just require a bit of tightening. Worst case, you have to back off the nut and reseat the seal. If its not leaking in the first ten minutes it probably wont leak at all.
