Good point...but not all regulators have a pressure release valve and an EOT dump can be disasterous.....

I change mine out at about 700 LBS because I know I will only have about a week or two maybe three until it empties completely.

It's good to have a spare tank in the garage. I have a 5LB that I keep as a spare and use 10LBers on all my tanks.
