Don't close all the valves, one should be wide open at all times. The deepest longest run should be wide open and the shallowest should be closed the most. These compressors can push air through thousands of feet of tubing. I'm sorry you are having such a tough time. I emailed Ted, hopefully he will get on the forum and help you. He is the best when it comes to knowing our systems inside and out. Don't get to frustrated... we will get your system up and running perfectly no matter what!!
