: Glad you were able to fix the nipple. I’ll tell you the few tricks I know for getting a bottle off a fill station when it won’t bleed out. First lets look at your tank and fill station. On the scuba valve, you see an oring, this is to form a seal with the fill station. Now look take your fill station and mount her… on your scuba tank. Don’t screw in the knob yet, first notice how much the fill station sinks into the valve to make a tight fit. That 1/8” of steel is not going to break or anything. Now when you screw in the knob, you screw in a lot, this means that when you break the airtight seal under pressure, there’s still almost the whole 8th inch inside the scuba valve, so it’s never going to pop off (or fly off at high velocity) under pressure. What this means is the sudden release of the seal can and usually will jolt the nipple valve into alignment. First, though try rapping on the nipple a few times while bleeding. Sometimes that kicks the valve closed too. So what I’m going to explain to you, is safe. And yo u’ll see why as I explain. First thing- Fill bottle. Turn off tank (bulk tanks are called tanks, airsupplies on gun or remote are called Bottles), open bleed valve. Symptom- Bottle doesn’t stop bleeding. Shut bleed valve. Try again. Shut off bleed valve. If you can easily, remove gun from bottle. This will make it easier to handle until you get the knack. Make sure scuba is off, then unscrew the fill station knob. All you need to do is break that seal, so there is no way at all that you will pop the station off the tank. As you unscrew, you’ll suddenly hear a loud Pop accompanied by the sound of sht being dumped into your friends pants. At this point the fill nipple valve has either been jolted shut or it’s still hissing. If it’s still hissing, then you have to let it bleed out and open up the nipple. You should be able to remove the bottle now that the internal Psi is not trapped. Now the thing is when you pop the fill, the Oring in the scuba valve will usually pop too. Not busted, but out of it’s placement. So look for it, and push it back into place with your finger. Sometimes it’s really hard to unscrew. If it is, then you can try bleeding it a little while you’re unscrewing. You may find you need to use a channel lock or something large and tool-like to get it unscrewed. If this becomes the norm, don’t tighten the fill station more that just enough to make the seal, and you’ll have less unscrewing to do to pop 'er. more questions? you can email if you want.
