I just bought a keg setup and had my 5lb C02 tank filled at a local welding shop. When I got the tank home I did give the tank a quick open to let the pressure release for a quick "psst" (sound effect) just to check it out and then again to show the GF. When I hooked the tank up to the regulator it now shows just above 500psi at approx 40 degrees F. However, this is at the "order new tank" portion of the gauge. I got all the equipment from KegConnection and the shop I filled up at was recommended on the "BURP" website. My questions would be the following:
1) Is 500psi low for a refill, if so, would opening the tank a couple times do it?
2) I paid $27 for the fill-up including a "Standard $10 Hazardous materials Fee" that seemed way more expensive that what I was told it should be, is it?
3) Can you just fill-up at a paintball shop or is there a different because they use liquid C02 and kegs do not . . . ?
Any help would be great!
