Pin Valve on HPA tank is not working

[Abel]

Ok...this made me really mad. I unscrewed my HPA tank from the back of my mag and the pin that is in the pin valve stayed down in the valve thus leaking out air. I tried pushing the pin back down with a screw driver to see if it will pop back up but to no avail. What could be wrong and how could i fix it

I wouldn't try anything your self, unless you are a trained airsmith. there is alot of power in air tanks and if you play with them with out knowing what your doing you could hurt your self or somebody else.

Somethings yo could do is
1.)Is the tank new perhaps there is a warranty on the tank or send it back to the manufactuer

2.)Take it to a airsmith and let them fix it.

let the air drain all the way out or push it down a little and slide it towrds the middle. my friends pmi hpa tank does that some times and i do that to it and it will usually pop up all the way and stop.

ok empty the tank, then put a little oil on the pin, let it soak down and then push it in and out a bit, that has been the fix to many co2 tanks that I have owned,
