Trying to get my pool going for the summer. I have a 25k gallon pool with a Hayward super pump and sand filter. I have a skimmer and bottom drain. I knew we had to change the sand this year so we did that. Filled the pool up, hooked up pump, filter, and piping. Filled the pump basket with the hose for a solid 2-3 minutes. Started it up. After running for several minutes, the pump will not prime and water won’t circulate. I have some air bubbles coming out the nearest jet. When I turn the pump on, I can definitely hear the motor running. I can hear a suction when I open the cover. If I let it run for too long, the water starts warming up, but still no circulation. I assumed it was an air leak on the suction side. I have changed out the pump cover gasket and the union o rings and lubed everything up with silicone lubricant. Still nothing. Unsure of what to do next. I did have trouble clearing my pool last year, I assumed it was due to a dirty filter.
