If you do find yourself the owner of one with an expired Hydro, call a local dive shop or your local fire dept to find out who does their hydro testing.
The tanks are good for 4 years from date of manufacture,then only 1 hydro test good for 4 more years. So a tank has a 8 year service life. I have many tanks that look like new that never left the shop but can't be re-tested.
The Laws of Thermodynamics say:
Zeroth Law: "You must play the game."
First Law: "You can't win."
Second Law: "You can't break even."
Third Law: "You can't quit the game."
Do you wanna Play Thermodynamics ???????? I forgot "you must"
