As you know, everyone’s brewing technique is different. We brew in our detached garage/barn, then carry the boil kettle full of wort to our basement (150’ away), then chill wort and transfer to fermenter, Pitch yeast and ferment in the basement. And since it’s two of us, we clean as we go. And by the time I have the yeast pitched and finalize my notes, my wife has finished drying the equipment and 5 minutes later everything is put away and brew day is done.Adding pumps would add another cleaning element to a well oiled technique.
Somewhere around our 5th brew, I added the pump to the system. Cavitation, extension cords, more cleaning didn’t improve brew day. Ultimately, after two brewdays with the pump, the pump is now in storage. As time and technique change, it may find it’s way back into the system, but I doubt it.
