A&A - pipe vibrating when changing pop-ups

[Jamecl]

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?

I added a video:

Maybe call A&A and ask them.
Are you the original owner? If so, you have a lifetime warranty on the system.

What rpm is the pump running? Maybe lower it just enough to stop the vibration. Could be you have too much flow thru the water valve.

Show us a few pics of the entire equipment pad.

I’m not the original owner. I adjusted the speed down a couple hundred rpms and it’s definitely better, not perfect. I added photos.
