So, we just recently purchased a 1 hp Hayward Pump with a cartridge filter to replace the inadequate filtration system that came with our 16x48 Intex AG pool. We have been extremely happy with it and it is SO much more powerful than the little pump we had before.
I didn't even realize that we have a potential problem until I saw some threads here about air bubbles. We have lots of bubbles that come to the surface from the return into the pool. The water in the skimmer basket is not "still" or full to the top. It is "churning" with lots of bubbles. Other than that, I see no issue with the pump. The suction is super strong and the return jet is powerful.
So, we have a problem somewhere, though? Should the skimmer basket be filled to the top with zero bubbles and zero bubbles coming from the return? Honestly, as I said, if I hadn't read about it here I would never have known. I've scoured the pump Owners Manual and it makes no mention of air bubbles at all.
We just checked the lid to the skimmer basket and it was on so tight that it took us a bit to loosen it. I don't see how air could get in? We also checked the little drain and tightened that. Would the lack of lubricant cause this problem? We haven't tried that, yet.
Its just a simple design on this AG pool...tubing coming out of pool and into skimmer basket and then running right back into the pool off of the cartridge. Not a lot of room for error?
I'd love any thoughts. This is driving me crazy!
