( I am a newbie first time pool owner ).I have 2 pumps, one for the pool and one for the waterfall. I cleaned the pump baskets last week and noticed that the pool pump was running whisper quiet So I looked at it this morning and seems to be running dry. There is no splashing water visible through the lid, just some fine particles floating. So I turned on the other pump (waterfall) and I can see and hear the gush of splashing water as it is on, but not on the pool pump.
My hot tub with spill over is working when the filter pump turns on, so my question is would the spill over work if the pool pump were running dry ?
