I've been brewing for about six months and I'm working on my single tier three keggle system. I had my buddy weld a coupling about 5 inches from the top of the mash tun. I plan on installing a Blichmann auto sparge. Would I be able to use this if I do 5 gallon batches? Should I consider brew hardware a loc-line? I would also like to recirculate. What is my best option? Thanks!
