Hello all, have an issue with my pool pump that just started this afternoon and I cannot figure out for the life of me. The pump was running just fine this afternoon when I noticed that the water stoppped flowing and the pump was making a noise as if it was trying to prime. I went to check on it and thats exactly what was happening- the pump was trying to prime. It would start running again, maybe to 90% or so capacity for a matter of 5 or 10 seconds, then the pressure would drop to zero and the process starts all over again. it kicks out a lot of air bubbles as it starts to run again, not sure where that is getting in to the system. Any thoughts on what to check here? Appreciate any help!
