'because I'm still getting extremely foamy pours two and three pours from the first, I don't think heat is the major cause of these problems.' I think you're right. If your fridge really is 32 deg. the foaming might be an issue of over-carbonation. Fully saturated, beer at 32 deg/12 PSI will be carbonated to 2.9 volumes (if you're dispensing with pure CO2, ...
The regulator will give you a reading of the pressure inside the keg, but will not release the pressure the way a spunding valve would -- you'll have to do that manually.
The carbonation process shouldn't matter with respect to your altitude. Inside your keg is a closed system. So the same rules of temperature and pressure applied will get you the same volumes of CO2. The rate at which the beer 'de-carbs' in the glass IS effected by your altitude however. So if you find that the beer is getting too flat to quickly, well ...
Just to be clear this is regarding steel or aluminium kegs... in the end they'll all fail at a high enough pressure but will they explode or will they leak first (not everything explodes)? In mechanics terms are they a thin walled or thick walled vessel. The thicker the wall is the stronger it could be but also longer the cracks are that can grow in it as ...
Just put a tool that fits this square hole and unscrew it counter clockwise (normal thread). A large enough flat screwdriver can be used between 2 corners, to. Inadequate tools could damage the plastic and make things more difficult. Find a good tool before you try.
No, you could not use 5-liter mini-kegs for a pressurized fermentation UNLESS you could replace the top bung with something like a Spundling valve, or perhaps a cask-conditioning style bung with a shive, and then you would knock out the shive at the appropriate time with a porous spile that would allow excess gas to vent. I can't find the pressure rating ...
