Glad to hear that your taking the valve and regulator in for inspection. CO2 tanks operate at very high pressures. A typical small CO2 tank is operating at anywhere from 860 to 1,000 psi, depending on the temperature in the room. Make sure that your valve has a safety release. At work, I've got photos of CO2 tanks that exploded and I would not have wnated to be near them when they popped off.
