    Obviously I am on the learning curve with tubing so I do appreciate the input. So 2 years back I had a 3/16 line and saw a tee with nice steady bubble movement moving into it, but rapid bubble movement passing through. from what I read I recognized this as a leak. So now I have learned that micro leaks can stop flow too. Still can get my head around why the lost of vacuum would prevent the sap upstream to empty out. Maybe the tap at the blocking point is winning out because its sap is feeding the flow and those above are not. Sounds like micro leaks are tough to figure out!

    The leak creates a lower pressure than the line beyond so that leak loss area gets pulled harder and first....Like pressure more air would go out there if not all versus the farthest hole or leak

    If there is a micro leak you will see air bubbles coming in. Maybe not real fast but more than normal.

    Our second year on are system,we have had some tee's at the drop line crack and had to replace.Sometimes if its at the tree you just have to tap the tap a little more.It is a learning experience.
