I have an inground pool with integrated spa and when the circulation pump runs, I have a steady stream of bubbles coming out of the outlets. I assume air must be drawn in somewhere on the suction side. However, looking through the clear lid of the strainer basket which is just ahead of the pump, I don't see any bubbles or air collecting. Also, when the system is switched (via electric valves) to circulate through the spa, I don't see any bubbles coming out of the spa outlets.
Any suggestion on how I can determine where this air is coming from? Thanks in advance!
