My pump is 6 inches to a foot higher than my pool. If your pool water was normal and you lost prime when the pump stopped running, then you have a leak somewhere that is allowing air to get into the system.
I've fixed my many leaks and I no longer loose prime when my pump is off. The leaks before the pump are called air leaks as they bring air into the plumbing when the pump is running, leaks after the pump are called pressure leaks and push water out of the plumbing when the pump is running. Either leak will bring air into the system when the pump is not running.
A few places to look is anywhere you see moisture or air bubbles or hissing sounds when the equipment is turned off. My leaks have been: leak where my pressure gauge attached to my filter, big filter gasket, filter gasket where it connects to my multiport value, my multiport valve spider gasket and handle gaskets, my multiport sight glass, jandy check valve before my pump, plumbing lines cut and not repaired correctly while installing speakers.
My equipment, plumbing and pool were all original (1982) when I purchased my house. I now have all new equipment above ground and new plumbing above ground.
