Shoot for 1-1/2"

[Ewesfull Acres]

I/and my son, have just finished our new lines in place of buckets, What might we expect per tap in sap volume on average, Our runs consist of 25 taps on 5/16. Running slight pitch to mainline to small diaphragm pump,(claims 25+ inches Hg,) One 3/16 line with twenty taps with great pitch. One 3/16 line with fifteen taps on pretty good pitch and one 5/16 line with 18 taps to drum with not bad pitch. I really don't have any idea yet!! Thanks for your help,,
