I need a bit of help on building my structure. I do 12 gallon batches, batch sparge, and have a few questions. My boil pot is 25 gallon custom pot I had given to me. It is 17" in diameter and 26 inches tall. I use a 100qt extreme cooler mlt. I'm going to use a converted keg for my hlt. I do have a march pump that hasn't been used. I use an immersion chiller that I thought I could wirlpool like Jamil. My question is can I use the pump to pump my runnings from the cooler to the boil kettle? If so how do you vorloph? If I go 3 tier I'm 54" to the top of my keg. I'm not too worried, but don't want to be on a ladder all the time. It would put the top of my cooler at 47", too high to be mixing. Would you build a 2 tier and gravity from hlt to mash tun and pump to boil kettle? Have never used a pump and will be my first multiple burner set up. I have 2-200,000 btu NG jet burners and want to make one structure, not a build full of regrets. Thanks I knew you would know.
