I am trying to determine my need for a pump with my set up. I currently brew 5 gallon batches and use a 10 g HLT, 10 g cooler mash tun, and a 15 g kettle to brew. I'm considering a pump for moving water from my HLT to my cooler. Right now, I have to pick up the 5+ gallons of 150 degree + mash water and dump it into my cooler, and I know it's only a matter of time before I dump this on myself in some capacity. My question is this: Are there effective alternatives to investing in a pump? I don't have the materials to use a gravity fed system to simply drain it down. Any suggestions regarding alternatives or additional info on pumps would be greatly appreciated! Happy brewing!
