    Default Guzzler Pump

    I have a guzzler pump on 300 taps and i get good vacuum most time -22-25". Sometimes though the sap just cycles back and forth about 4-5' in fron of the inlet.

    what causes that?

    thanks

    I have had plastic from drilling mainline get stuck in valves. I have unions on both ends. When this happens I take sap unhook unions an tip pump up n flood inlet valve. Usually works for me. Hope this helps.

    Don’t know if you’ve had the umbrellas out before, but if they were, make sure they were installed correctly.
