I have an above ground pool with a single skimmer which feeds into my pump and then a Sta-Rite sand filter. My problem is that when air gets sucked into the skimmer due to floating toys blocking it, the kids messing with the door flap, or maybe just intense splashing near the skimmer, the air builds up in the sand filter. This in turn causes air binding (as described in the priming videos) which prevents the pump from priming until I let some of the air out through the waste port.
So my question is: Don't sand filters have any automatic way to deal with air? The top down filtration design of a sand filter seems to be a natural trap for air. I would think that over time even small amounts of air would build up into a huge slug of air in the top of the filter. Should my filter deal with this somehow that I don't understand, or do I need some DIY engineering to fix this issue?
