After having my new Hayward EcoStar pump installed last Saturday I've noticed that when it's running at higher speeds there's an air pocket about an inch deep under the strainer basket lid, right about at the level of the top of the strainer. When I turn the pump down to low speed for a couple of hours it slowly goes away and there's virtually no air under the lid. There are no bubbles going back to the pool that I can see, though I haven't sat and watched it for an extended period of time. Should the strainer cavity be full to the top with no air pockets whenever the pump is running? All my plumbing is new as of Sept. 2010 and all fittings are tight.
Thanks for any help.
