Here are the details;
I did an all grain Hefe recipe which I had brewed previously with no issues. I used my new HLT which is a converted keg using Northern Brewers weld less valve, with a copper pickup tube I built, and a Northern Brewers weld less sight tub/thermo well.
I mounted the sight tube as low as possible in the keg, but of course the bottom dips down well below the sight tube mount. I filled the keg to the point where I could just see water in the tube, then started adding a quart at a time so I could mark the tube in quart increments. I thought about just adding a gallon and then measuring that on the tube and dividing by 4 and marking my quarts, but the keg is dented up enough that I felt it would not be accurate.
1st problem, as I heated the water (about 130-170 degrees) air bubbles started going up the sight tube and pushing water out the top. It only did a couple ounces, but still I dont like the idea of hot water coming out the top of the sight tube.
2nd problem, once I stopped heating the water, the level in the sight tube sat higher than it was when I filled the HLT, which Im sure threw off my water measurements.
3rd problem, how to account for the water in the hoses and pump? Example; I need a gallon, so I run the pump and watch as the mark on my sight tube goes down by 1 gallon and stop pumping. But, how much of that 1 gallon is still in the lines?
4th problem, at the end of mashing/sparging, I ended up with 1.5 gallons more wort than I should have (based on recipe done in BeerSmith, which is one I did before with no issues). I believe this caused me to miss my target OG (1.047), I hit only 1.032.
Any help on the above issues would be greatly appreciated.
