I have a question about tubing lines. I have a number of 5/16 tubing lines that daizy chain from tree to tree. At the trees midline I use T fittings. The perpendicular nipple is used for the tap. Is it important for the tap nipple to orientself itself straight up so that the sap from the tap drips down into the stream? I have not tried to orient them in any particular direction. I never seem to have very good flow on the tubing lines. Also how important is it to get the fittings fully inserted into the tubing. Up until half way through this yead did I have a tubing tool that could fully insert the fittings. All I could do using my hands was get the fitting inserted over the first ridge on the nipples.
