I like my equipment so far and have a hot liquor tank but the issue is my sight glass is set up so high on the side that I am at 3 gallons before the water volume is high enough to register. I have a Sanke keg that I can convert over to a HLT but I use one for my boil kettle and it is even worse. I don't think you can mount a glass low enough due to the way the kegs are made. Has anyone drilled the bottom and welded a 90 degree elbow with a pipe coming out with another 90 on the end of that and the sight glass attached to that? Better yet, does anyone have any pics of a converted keg with a sight glass that is set low enough to register at 1 gallon or even lower?
