I’m contemplating on purchasing a Blichmann G2 kettle and there are two options. 1/2" Barb for Drain Valve or 3/8" Barb for Drain Valve. Which would be the better option and why?
1/2 inch will drain faster. What are you draining into? A chiller? A fermenter?
+1 to half inch. You can always go slower.
I am going to drain into a fermenter.
+2 for 1/2". If you ever want to get a pump you’ll need it.
Maybe this comment should go in “unpopular” brewing opinions. My SS BrewTech 10 gal. kettle came with a nice, three piece valve on the drain. But since I plumb the drain to a transfer/recirc. pump, I never used the valve. It was just a place for crud to collect and another thing to have to take apart and clean. So I took it out of the system. If I ever have to block the line to the pump, I can use a small vice grips to clamp the hose.
