Filter problem?

[marybee123]

I have a 16X32 inground concrete/fiberglass pool. This is the first year I've attempted to open by myself. I flushed all the antifreeze out of pipes and started the pump. I noticed that my filter has no pressure reading though and the little glass in back is just half full of water and not moving. I didn't do anything with the filter when opening. Did I miss something?

Did you prime the pump?
