I've had my aluminum deco bottles set up in my heated garage for the year as I have not done any technical stuff this year. My aluminum 40 filled with O2 hasn't been touched since I put them there last March.
I leave the house at 3pm and return to at 4am and hear a hissing noise coming from where I keep my tanks. I noticed that the garage heater had not kicked on and it 43° inside instead 60°. I try and find the hissing sound and see that it's coming from my pony tanks. I see that it's coming from my pure O2 tank and turn the valve off and it has no more give to turn back. I wrench it back with force and the hissing stops after 10-15 seconds. I get the heater back on and the next day I see that I lost 2000psi out of a 3000 fill. I live alone and the garage is locked up and attached to the house to boot.
Is it possible that the Cold could have somehow caused the valve to go? It was a slow leak and no moisture or frost on the valve to indicate a rapid leak. It seems that it must have been on for 3 out of the 13 hours I was at work.
