Just curious, at the end of the day do you:
A. Turn off pump, open valve and let vacuum rush back up the line.
B. Turn off pump, sit and wait until vac neutralizes on its own.
I've got 112 taps on one sugarbush, shurflo pump pulling 17", 3/4" line is mostly full, no leaks in system, so it airlocks, as the lines fill vac drops to 13", pump dumps sap like crazy, then stops flowing until it fills enough line to overcome the vac above.
All taps have check valves. Hate to throw the valve open, but its due to freeze later. Not fond of leaving it running due to risk of ice. Just curious what others do.
