I'm in the process of building a new all grain rig. I will be using 3 burners and would like to run them all off of one propane tank. Where can I find a 3-way propane splitter? Also, is a standard tank of propane able to fire 3 burners on full blast simultaneously? I do not plan to ever have to be using all 3 burners on full blast, but if the need every arises I'd like to know...if not I may consider just buying more propane tanks. I'm using 3 of the big BG14 burners.
