Definitely no plugs in the skimmers. Water level is above the skimmer. Valves are open and I lubed the basket strainer gasket.

The pump pulls some water but it never gets more than half full.

I also Teflon taped the union joint closest to the pump and had tightened it. I was really hoping the problem was being caused by the pump seal. I just got my go kit in the mail so I'll change everything out and see what happens.
