When you first setup the blumats you soaked them for at least an hour correct?
When you assembled the cap onto the blumat did you tap the cap underwater to make sure there were no air bubbles in it? I like to put the blumat together under water in a 5 gallon bucket to make sure there is no air inside the blumat.
If that is all good the next thing to check would be that there is not air trapped in the lines, I like to open the blumat all the way and tap on the lines to knock loose any air bubbles. I let it run for about 15 seconds after I don't see any sputtering. I start at the blumat closest to the res and work my way down the line.
