I took apart the low pressure gauge and I was turning it back and I finally got it to stick at 0. I have yet to hook the regulator with the gauge to my CO2 tank so I don't know if the gauge is fixed or not.

On another note, the outlet diaphragm valve seems to be inoperable. I can't turn it. Is it because it will only operate if you have pressure behind the valve or should I be able to open and close the valve now regardless if it is hooked up to the CO2 or not?

One final question, what exactly is the output range for the Matheson 3813? Is it up to 30 psig or 60 psig?
