    Is there any chance the RPMs turned out by the pump are causing the impeller to spin faster than it is designed to work at? (wild guess)
    Impossible.

    What about the impeller wear, I've checked it out and made sure it is clean, is there some symptom I might be missing?
    I don't think that would cause the issue.

    Sounds like an air leak but why it would be periodic if isn't a weir or water level, I do not know. Sometimes, suction side leaks will pool around the broken part of the pipe and so will appear to work for a while as the water is drawn back into the pipe but after than happens, it should just suck air.

    Thanks again. I've had a couple of other people look at it. They think the line from the skimmer to the pump is either cracked or blocked. This is an older pool and currently the skimmer is the only source for the pump to draw water from. This is also true for vacuuming. I've dealt with blockages before, but this one (if that is what this is) is different due t the amount of water that is reaching the pump. As stated the cleanout pot is never empty and circulating water is always present...it's just that circulation and water level is diminished.

    Interesting note. When I place my head to the ground about the area that a PVC elbow joint should be I can hear a lot of swishing and bubbling noises. Closer to the skimmer I hear a gurgle from time to time. We'll see. A pool guy is coming out tomorrow to pressure test the line and then blow it out if able. Trying to locate a plumber that can scope the line also. to see what we're dealing with.
