    Assuming you aren't using a vacuum pump, and are relying solely upon natural vacuum:

    1. Use 3/16" line from the top of the slope to the bottom where you have your 3/4" mainline. These lines...

    If you like rigid tubing, Leader 30p is good. We've been switching to more flexible lateral line material recently, and found Lapierre and CDL tubing to work nicely. Haven't really tried H2O or...

    There hasn't been any research that I am aware of looking at timing of replacing spouts in the woods as it affects sanitation. We typically do ours in Nov-Dec, and tap in Jan-Feb. We used to do...

    That depends upon your goals. In general, a single standard membrane will max out at 4.7X the sap concentration at the stated flow rate (400 gpd processing rate I think is what you said, but this is...

    It's been an absolute game changer for us, especially when combined with HyperBrix concentration. We boiled 5 times total in 2019 (+ a boil-out) and 8 times in 2020, and made over 3,000 gal each...

    1" mainline provides much more room for vacuum (air) to move across the top. We won't put 3/4" in the woods any longer. The margin for dips is just too small. Let's say you're 3/4" pipe is 1/2...
