So I just started my brew day with my newly built brew stand. I have it rigged with propane lines. Everything is going great then Bam. Burners go out . Switched tanks, turned everything on and off a couple times. Still nothing. I switched the burners directly to the tanks, so everything is still going. It seems like the burners have no pressure when hooked up to the stand. Everything is Teflon taped and had pipe sealant. So I don't think it's aleak. Any thoughts?
