Had a very green pool opening. Finally got the pool water blue, but now just very cloudy as the filter tries to clean it out.
After changing the DE, my filter's pressure builds up and waterflow stops within 4 hours. To be expected of course, but something that seems a little strange is that when I turn the pump off, before I go to bump it (or switch out the DE), I open the air pressure relief valve, and there's always a good deal of air that gets released. I don't have any water loss. I don't have bubbles in the return line. I don't have an air bubble in the pump's water pot. I've got plenty of water in the pool (top of skimmer). But somehow air is getting in the filter. Where would it be coming from?
Often, I can just release the air, then close the relief valve again and start the pump, without even bumping the filter or changing the DE, and immediately I'll get water flow again and a drop in pressure by at least 5 psi (not always, but often).
So I started reading around about it. I can see that it should not be happening. But I don't know where the air would be coming from. I recently replaced the pump basket gasket and lubed it up and also lubed the other gasket on the pump near the motor housing. Could it be coming from elsewhere on the pump? Maybe the line between the pump and the filter?
One thing that does happen is I hear a weird air straining noise in the middle of the pump after I turn it off. Not sure exactly where it's coming from though. Is this most likely causing it, you think?
