Is it normal to keep getting air?

Hi Dave,

Actually I think the skimmer is higher than the filter. The solar heater is sitting on the ground and the pump and filter are sitting on the ground so the filter is maybe around 3' high. The pool wall is 52" and the skimmer is only a few inches from the top so I would think it is higher than the filter.

I see what you mean about it not being the air flipping the basket and that makes sense. When the pump is on, if there is air in the filter, it will get compressed and when the pump stops, the air will push back and cause some water flow back through the skimmer.

The solar heater on the ground doesn't help explain why I don't get air when it's on.

Maybe air is getting sucked in from the flex hose joints?? If this is true, I don't yet see why it would be different having the solar heater on or bypassed. Anyway, you've given me something to think about. Thanks.

Peter,

I apologize for overlooking the fact it is an AG pool....even tho you posted that in your first post, I chose to be a dummy and overlook that fact.

I'm gonna "cipher" (Southern talk) on that a while and if I have anything constructive to add, I'll post back.

One thought I had is that the pressure on the filter gauge goes from 10 PSI in bypass mode to about 15 PSI when the water runs through the solar heater. With a higher pressure, the pump faces more resistance and so wouldn't that mean that the GPM would go down slightly? Maybe in the higher GPM (bypass) case, since it demands more from the suction side, it might be sucking air in from one of the hose barb fittings or the union between the pump and the filter. I should check the fittings on the suction side of the pump and filter to make sure they are all good and snug. The weather has been really crappy up here so it may be a few days until I can get out to do this. I'll update if I find anything.

I see in another thread that others have problems with the skimmer basket moving and a rock in the basket seems to be the solution.

Thanks for your help Dave.
