Was vacuuming to waste this morning after insane storms here in PA. Everything was working fine. Water was down to the height of the skimmers so I stopped to fill the pool. After the water height was good turned pump back on but it won’t prime. Checked everything I can think of: skimmer baskets clear, main drains don’t look blocked, pump basket is clear, o-rings have no damage, ran hoses directly in the skimmer lines, fished around the impeller but it seems to spin fine. It sucks the water from the pump basket fine but nothing from the pool. Anything I’m missing? I thought maybe a clog but it’s unlikely the main drain and both skimmer lines would all be clogged. Plus it was running perfectly fine this morning. I’m out of ideas.
