I'm trying to prime the corny with sugar. I bought a pressure checker and was told at the homebrew shop that I could prime as if I was bottling (3/4 cup) and then lower the pressure to 10# each day, until it stayed at 10#. I was told that the pressure would keep rising each day and that I just need to keep lowering to 10#.
Well, I seated the lid at 30# and then lowered it to 8#. It's been sitting in a room at 65-70 for four days and the pressure just stays at 8#. After two days, I thought it may have been leaking so I pumped 30# again and then dropped it down to 8#. So basically, no activity after four days.
How much pressure will kill the yeast? And should the pressure have gone up after four days?? Could pumping it up to 30# a second time, even though it was temporary do any damage?
NOTE: I primed with 3/4 because I wanted to bottle some of it.
