I was having a problem get the air out of my cooling lines. The res and pump are at the bottom of the case. When the pump was shut off the air in the res would go back up the lines to the highest point in the system. So to fix this I add a stem to the return line in the res so that when the pump is turned off the line would be under water. This is my first watercooler and I did research for 2 month before building and installing. I would like to share this with other people starting up was watercooling as I have not see anyone talk about this before. Here is a before and after pic to give y'all an ideal what I'm talking about.
