Hello everyone, I was having Dick's Sporting Goods Fill My 20 Oz. CO2 paintball tank yesterday and when the person was filling the tank he said it would only fill up to 7-8 oz. full not the full 20 Oz., what would cause a tank to not fill completely up with no damage to the tank or visible damage on the tanks valve? The tank was fully emptied out of CO2 before I had It filled again, which was about half an hour.
Would a CO2 tank being in the sun affect its filling volume?
Also I could depress the tanks valve stem and it bleed the little air out with no resistance.
20 oz. CO2 Tank Not Completely Filling?
Sounds to me like the person who was filling it didn't know what they were doing. Did he chill the tank beforehand (add some CO2 then dump it)?

I don't think he did. Im assuming he didn't because the tank had a bunch of frost and it started to sweat after he gave up on the tank, then he proceded to screw up my friends tank.
If it had frost on it, then it was chilled and should have been chilled enough to be filled. Reading the post, however, it seems that he filled it then unfilled it multiple times, no? The only other option (assuming the guy had at lease SOME knowledge of doing this) is that his tank was nearly empty. How did he screw up your friend's tank?

I think he said the frost on the tank was the blow by when he took the remote hose off, and he did try filling it multiple times. But he said when he was filling my tank it would fill only 7-8 Oz. then it would just release all of the air. And about my friends tank, my friend didn't really go into depth about how it was screwed up, but he made it sound like it just didn't work like before the guy filled it up.
If he said that, then he didn't know what he was doing...
On a standard CO2 fill station, there should be no reason for CO2 to produce 'blowby' on the tank. Not only that, but when you put the cold CO2 into a bottle, condensation will form on the outside of it. If he has ever filled them before, he should have known this.
It makes no sense to me that your tank would fill to about half, then empty itself. I've filled countless CO2 bottles and have never seen this. Either it holds the CO2 or it don't, which means that it would have began dumping the moment the CO2 begin to enter the tank. You could have a bad o-ring on the lip, but even that would make it dump instead of holding partial CO2.
Now, if he filled it, then blew the o-ring, this could have happened, but that would have been know, too, because those tend to be rather loud when the blow. If the o-ring was damaged prior, it may have caused a slow leak, but this would have only been seen AFTER he turned off the main CO2 supply, but before he removed the fill station and not during the actual filling process.
With those details, it sounds like the guy may be using a faulty fill station (still trying to give him the reason of doubt).

The only thing I could think of is that his main tank was almost out and equalized with yours at 7-8 PSI, but that's not likely and I think he'd notice. Go somewhere else and ask them to fill it. There should be no problem. If there is, get a new tank.
