Hi Gunner,

Your system sounds good - the thing that makes it work is the 3/4" lines to each and every row, the orifice is at the end of this 3/4" line if I understand you correctly, and then you probably have  the same length line from the orifice to the totally tubular (which has very little down stream pressure drop at the orifice).

Schematically this is about the same system I was describing but with the "Redball" monitors.

What you have done differently from most folks is used a 3/4 line (which acts like a manifold and has little pressure drop at 5 or 6 gpa) from the monitor to the orifice. Most folks put the orifices in the center of the planter and/or run small lines out to each row. This can cause a lot of problems. But your system sounds good.

Good to hear from you. Just the WI dot now?!
