Brewers, I purchased a weldless thru fitting for my boil kettle. It's a 20 gallon bayou burner kettle. I want to put in the thru fitting and was wondering how far up from the bottom can you safely locate the hole for the pass thru? I would then put an elbow down to within about a 1/2 inch from the bottom of the kettle on the inside. Any thoughts and or suggestions. Tried siphoning last night and it takes too long. 12 gallon batches. Thanks all....Simie
