I am currently converting to electric, and think that having a bottom drain for the brew kettle would help tremendously for priming the pump and also clean in place. My question to those with bottom drains: how do you plump the ball valve for the bottom drain? I want to put a 1/2" ball valve on the bottom, obviously directly connected to the bottom of the keg is no different than my current dip tube that sucks from the bottom of the keg. But what about plumbing a 10" pipe from the drain in the bottom of the keg to the ball valve? Is the 10" of wort in the plumbing that is not boiling cause problems?
