Priming these things can be a pain but usually they get going. You can avoid having to prime it each time by shutting the valves before doing your water change.
I did not replace the impeller, just the cover. I did realize after this post that the intake strainer had come off and was floating in the tank. I checked it and it is cracked to the point where it won't stay on anymore. I need to get another on of these now and don't want to try and prime the unit before doing so.
I will get an new impeller shaft at the same time and see if that helps. Thanks.
