Hi, I've recently brewed my first beer and have been enjoying it for a few weeks. There's about 25 pints left. The pressure in the keg had dropped recently - possibly helped by the drop in temp. I've topped up the pressure a couple of times with a carbon dioxide cylinder. But tonight I possibly put too much in and the valve has frozen open. It's been about 1 hour now and it's not changed. I've kept the co2 cylinder in place in an attempt to keep some pressure there but i'm worried it won't be a good seal and the co2 will leak out and cause my beer to go off.
Any suggestions please....?
