My backpacking cooking setup has always been white gas and then more recently alcohol stoves up until my most recent purchase of a canister stove, the BRS-3000. I have tested it a few times and all has been well... until today. I was warming two cups of water for tea in some pretty strong wind and after about 3-4 minutes I heard the flame go out despite the flimsy tin foil wind guard I am using. The water was plenty warm for tea so I preceded to break everything down. After I unscrewed the stove from the canister, fuel was heard leaking from the canister valve. I proceeded with caution and left the canister in a safe location. I came back twenty minutes later and it was still leaking.
I am wondering what caused this? I am leaning heavily towards the canister malfunctioning, as it seems more likely than the unscrewing of the stove causing it. Any thoughts? I am now wondering if I should've screwed the stove back onto the canister and then removed again to see if it would then stop leaking. The canister was a 220g Coleman from Walmart that had been used for three other cook sessions without incident.
