if my pressure is different when not attached to a keg than when it is attached, is my regulator busted? I have it set to ~10 then attach to the keg and it drops to 5 psi. Anyone ever experienced this?
This means that co2 is moving from tank through the regulator. Usually there will be a noticeable change in on the regulator when there is a large difference between keg and set pressure. If you leave it hooked up does it eventually get up to the set pressure? If not you probably have a leak in your system.
