Bumping this. I have a Jandy 2.7hp VSP and when running at 2400 RPMs it's basically fully primed with only a few microscopic bubbles here and there.
However, from 5pm to 9am I have it run at 1400 RPMs and the bubble grows slowly overnight so much so that it does stay primed, but the air bubble ultimately encompasses basically the whole translucent dome.
When it switches back to the 2400 RPM level at 9am, it eliminates that air bubble within like 5-10 minutes tops and operates full of water again. My nearest return also lets out a steady stream of very small bubbles after a while of operating at 1400 RPMs. Basically, once the bubble in the pump gets big enough (after a few hours).
This is all while I bypass the heater. When I have the water go to/through the heater, it doesn't get quite as fully filled with water in my pump at 2400 or 1400 RPMs as it does when I bypass.
Anything to be concerned about? I've tried saran wrapping and the hose trick on the lid, pump drains, and gasket leading into the pump; none of which seem to make much of a difference.
