Hayward Pump at 0 PSI

[Superfrank2727]

So, my wife went swimming today and unplugged the pump since she doesn't like the jets. When I got home I went to get water to test the chlorine and pH, noticed this and plugged it back in. 0 PSI and weak pressure from the return jet.

I tried to reprime the pump but unfortunately I can't seem to find the pressure valve, so whenever I remove the top seal the water just gushes out. I don't have a valve that I can close from the skimmer so I blocked it with a skimmer plug.

I tried letting run for a bit but still nothing. I tried backwashing in case the Sand filter was clogged. It was dirty but not terrible.

After backwashing the water level is a little low on the skimmer but it seemed fine before that. So I might try adding more water but I hate doing that because my well water is alkaline and high iron.

For reference I have an 18 foot Cornelius above ground pool and a Hayward Powerflow LX pump hooked up to a 100 lb sand filter.

Good morning. Are you still having the problem? I'm a bit confused here because with an AGP and the waterline being so high above the pump that is at ground level, water should flow downward easily to the pump to maintain prime. The only thing(s) stopping it would be a low water level in the pool, a blockage in the suction line, closed suction valve, or that skimmer weir door getting stuck closed. Am I missing something?

I still am. I'm going to try adding more water tonight to see if that solves the problem. Haven't checked the door yet but I will do that too. I don't have any valves to close so that shouldn't be a problem. I don't think any of the hoses are clogged.
