I have a low profile A&A 6 port in-floor pool cleaner. When it advances to the next set of pop-ups, the A&A 6 port unit vibrates along with the pipe coming into the unit. This doesn't seem to happen on all the ports and it doesn't happen on a lower motor speed. I've attached a video. You really can't see the vibration in the video, just the sound, but I can feel the ground shake, if I'm close, when it happens.
Any ideas?
