I tried to open my pool yesterday, and my pump won't prime. When it's turned on it looks like its starting to draw water but then then the water all drains out faster then it comes in. The pump was in a detached garage all winter, and I realized yesterday that I missed one of the drain plugs and there was some water in there. If it froze and cracked something where would I have to look to figure that part out? I tried resetting all the o-rings in the pumps and unions. It was pretty dark by the time I got enough water in the pool to fire the pump up, so I might have missed something. That said I'd like to go home from work today with some trouble shooting suggestions.
