I’ve noticed that when people are playing in pool (mainly jumping around, resulting in a “wave” action in the water) occasionally I’ll hear a knocking/thudding sound that appears to emanate near the skimmer & portion of plumbing that is above ground, you can feel pipes vibrate slightly. I turn pump off as soon as I hear it & wait a few minutes, start back up & it’s gone. Does the waviness of water going in single skimmer doing this? Some sort of air lock? Any way to prevent from obviously not jumping around? Thanks!
