put out another 400 taps yeasterday all gravity, still more to do but have a lot of trees to cut off lines.
I redid my AOF tubes. when i first did them i must have had a hold of the dumb end of the tape measure the nozzles ended up around 8 to 10 inches below pan and still only did 30/35 gph. well this year they are where they are supposed to be. I had concentrate gauge set around .5/.7gpm and we ran out of sap in head tank. dialed in concentrate to 1gpm and was keeping up with it. So according to that Im boiling of 60 GPH.
