I bought a new corney. I have another one and the blow-off safety valve has a ring so that it can be pulled to release pressure. That is how I've always purged that one, but my new one has a blow-off that is, somewhat, concealed and has no ring. Basically, I need to know if there is a way to manipulate this valve to bleed off pressure or can I fill through the out tube and purge through the in tube, or crack the top a bit?
