Another note: I tried the DDM "lift the reservoir" method when I replaced my recently replaced my water pump. I couldn't get all of the air pockets out that way. (Note, though, that I didn't have the check valves installed.)
An Airlift is really the way to go. It makes the entire process take about 5 minutes and will quickly let you identify any leaks in the system.
