I seem to be having a significant amount of surging in my pool pump- I'm afraid to keep it running. The pressure gauge seems to never settle down. I've never opened this pool before- it was always done by my father. The pump is new- it was replaced last year. I seem to have a good prime on the pump, but the surge is preventing me from running it constantly. It ran fine last year when my dad hooked it up, but I think I might have missed something. Does anyone have any advice?? Thanks in advance!
