I have a hayward 1 hp pump (powerflo LX). I'm assuming it is self priming but I don't fully understand what that means. If any air gets in the basket on the pump, usually it makes its way out, I think that means its self priming.

Anyhow, the whole above water level, below water level thing blows my mind, I might be due for a new pump so I want to fully understand it.

My pool is 1/2 underground to a little more than half underground (ground around isn't perfectly level. The pump is ground level, I have PVC that goes a foot underground, goes about 8 feet away, and comes back up. I believe the water line is above the pool pump by maybe 6 inches, maybe less.

Do I need a self priming pump? Can I get an inground pool pump that is not self priming?
 
If the water level is above the pool pump inlet then you do not need a self priming pump.

I think you will find most, if not all, pumps listed as an in-ground pump will be self priming.

For the situation you described you can use either type of pump.

I have used a Waterway Supreme and Hayward Powerflo for our in ground. Technically they are for AGPs so that the higher waterline makes for easy prime. Mine was installed that way. It works, but I also have a check valve before the pump so the pot stays full. With a waterline slightly above your pump, it sounds like you should be okay as well.
