    Default Pulsating Sap Flow

    As I was tapping recently, before I inserted a spout, I observed on some trees, a pulsating flow of sap as if there was a heart pumping it out of the tree.

    What causes the pulsating?
    2023 - 2' X 6' Smoky Lake Products "Silverplate" evaporator + Increase taps up to 500
    2022 - 295 Sap Sak taps - Sold sap.
    2017-2021 - Didn't tap.
    2016 - 150 Sap Sak taps - Sold sap.

    It's not likely pulsating, but rather a little builds up in the tap hole or in the tap, and as it builds up it eventually flows out.
    Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
    Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
    Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
    After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
