Been working on a multitude of issues.... all but one has been solved.
Have a pool with flow-over spa attached. Every time the pool starts up in the a.m. the pump has to self-prime. Although the pump is designed to do so, it still is extra wear and tear on the equipment.
I can finally say there are no WATER leaks in the system. Does anyone have any suggestions to isolate where the air can be leaking into the system when there is no drippage? I have a pump / filter / heatpump / salt system.... in that order. Again, no moisture around any of these items - with the exception of the heatpump only when it is running. Thanks in advance.
