    Default Sap Ladder vs. Sap Lifter

    I want to eliminate about 130 buckets by putting the trees on vacuum, however the Lot doesn't have much slope and I need to raise the sap about 5 feet to cross a river and tie into the system on the other side of the river. I have a surge alamo vacuum pump and I can pull 22-24" depending on how much oil i put through it. The question is for the money, is it better to just put in a sap ladder, or is it better practice to use a sap lifter. I don't have big potential for more taps above the lift point, maybe 200 max. Interested in any thoughts or experience with either ladders or lifters.

    2022 - 500 taps and hopefully an RO so so i don't have to throw out any sap!
    2021 - 48 Gallons - new pans, new arch, lots of new taps and tubing
    2020 - 32 Gallons
    2019 - 27 Gallons

    they both work well. oversize the ladder, or use a lift. i like the lift a little better as the vacuum seems to be more consistent behind it, because you have a separation point for air and sap. going to replace 24 more ladders this year with 2 lifts if i can.
    4000 taps on vacuum, just trying to get a little better every year.

    There is some recent research out of Cornell I believe, about doing reverse slope without sap ladders or lifters. Results were decent for small changes in elevation such as what you mention. May be worth a read if you can find it.

    It (and several other thins) can be found at: https://cpb-us-e1.wpmucdn.com/blogs....2020-final.pdf Bottom of Page 6 under "Flatland System." An interesting concept...should be considerably easier to install than a traditional ladder or lifter. Only one year or results so far, so more research will be needed to ensure it works well under a variety of conditions, but looks promising so far.

    Thanks, i'll take a look at it. Im at the point where i need to either buy new buckets or install tubing, and if i don't need to buy a lifter the tubing will be cheaper than buckets. And of course since my labor is free, lol.

    I think i can replicate the setup from the picture that is included in the paper, I guess it wouldn't be hard to convert the uncut mainline setup to a traditional sap ladder if i find it's not yielding good results, i'm kinda excited to try it now! thanks again DrTimPerkins!

    I have a section of woods i am going to try this setup on as well. I wonder how different lifts and number of taps would affect this. Said they were lifting 4ft every 60-100 ft. Not sure if this was due to terrain or what they found to work best. Also from the picture used one star fitting top and bottom with 5/16 lines.

    I was thinking about that too, because i don't have a hight tap density, how many taps need to be above each lift in order for enough fluid for the lift to function well. I guess i'll see? lol.
