Why would you drain the wort to a keg, then pushing it back i to the kettle?
Because I want to sparge, and I can't lift the stupid malt pipe high enough when it's that heavy. I drained, lifted, and was ok. But next time, I'll just heat the water in the Brewzilla, pump to my old MLT for a full volume mash, then gravity drain back. Turns out that I can't do a full volume mash in the 'all in one' but the next biggest size was way too big so I'm going to use it as an HLT and boil kettle.
