Hi, new pool owner here. I have been watching your video's on youtube for about a year now. They are very informative and helpful, so thank you for that! Anyways, I have been having issues with my pool since we bought our house 2 years ago, with water chemistry to equipment issues. So far, I have replaced the pool pump and the cleaner this year (2018). The pool pump is a Pentair 3 HP Intelliflo VSF Variable Speed and Flow Pump and the cleaner is a Hayward Aquanaut 400. My questions: First, I have noticed large air bubbles in my ~22,000 gallon pool when the pump initially starts up, following with smaller air bubbles. After a while they disappear, but occasionally you will see some. I have been told that this is a sign of an air leak. So far, I have replaced the Push/Pull valve with an all new kit. Where would I begin to detect if there is a leak? Second, sometimes at the initial startup, my pump does not prime and reports an error after ~1min (see video). I notice water shooting into the pump basket, but not filling it at all. What could possibly by the issue here? Again, I appreciate all your help and keep doing what you're doing!
