From a production standpoint you should not run all individual lines from each tap. You should have a minimum of 7 or 8 taps on each line with up to a maximum of 25 to 30. With only 1 or 2 taps on a line there will not be enough sap in the line to create any natural vacuum.
First introduced to making maple syrup in 1969
Making syrup every year since 1979

Revolution syrup and max flue pan
Almost 1300 taps total with 900 on high vacuum
Bought first Marcland drawoff in 1997, still going strong.
