Hello and a preemptive thanks to all who respond. I batch sparge and use a 70qt coleman extreme with a hose braid (about 8 inches long) and a 1/2 inch ball valve. Each of my runnings is taking about 30 minutes (to collect 3.5 gallons each for a total pre-boil volume of 7 gallons). Does this seem long for this system? Any thoughts on how to drain it faster? Also, during my last brew day when I was calculating efficiency, I hit my pre-boil gravity pretty well but then missed my OG by a significant amount (1.057 instead of 1.067). BTW I was using one of the recipes from "Brewing Classic Styles". Any thoughts on why that happened. So many questions in this hobby! Thanks again,
