Ok I have read everything I can find and I'm about to give up...
We're talking ZERO prime. No water movement.
I've checked for air leaks everywhere that is exposed, cleaned all the skimmers, tried blasting water in every intake possible... Disassembled the pump and jandy valves, opened up the filter, opened the slide valve...
The only things I believe I have not eliminated are:
-suction side underground air leak or obstruction
-filter may be clogged (just got back from a trip), but I can't clean it without the pump priming
What else can it be????
