So I was thinking that i can start a siphon by using compresses air like CO2. My idea is a dip tube to within .5" of the bottom of a carboy up through a bung and to a siphon hose. then have a second hole in the bung with a tube just into the headspace to which i can hook my CO2 line off my reg to. Add pressure until liquid begins to flow out of the siphon hose. Then remove the CO2 and allow the siphon to draw. I know this has been done and must be common practice but what the heck is it called? It is really hard to research something without a name...
