Maybe you all can help me out. I have a a SS brew tech three vessel system with a mashtun, a hot liquor tank, and a brew kettle. It’s electric and I batched sparge. Been using this for years and it works great. I use one pump and just switch hoses. I pump the hot liquor tank strike water and underfill the mash tun. When the mash is done, I switch hoses and Vorlaf with my pump to the top of my mash tun and then pump my first runnings from the same hose that is going to the top of my mash tun into my kettle. Then I switch hoses and pump the Sparge water from my HLT into the tun from the bottom valve to underlay the water. Then I Vorlaf as above and then pump the second running into the brew kettle. Then I start my boil. In the last 10 minutes I run the boiling wort from the bottom Spicket through the pump back up to a whirlpool arm to sanitize The pump and tubing. When I’m done cooling, I pump wort into my fermenter. Looking online, it looks like everyone with a three vessel system has two pumps. Aside from less hose switches, why would you do this? What is the advantage? Seems like just additional hoses and an additional pump to have to clean at the end of brew day. Am I missing something? Thanks.
