Reducing vibration sound from wavebox

[hogben]

This equipment is still pretty new and I was wondering if there were any steps I could take to reduce the low vibration sound it makes when the wavebox pulses.

I was assuming there would be some splashing sound, surprisingly there is none, but instead that low vibration noise.

It's not very loud, but enough for me to hear from another room with a closed door.

The rubber ring around the outlet of the pump is on the inside of the box, is this correct? It was hard to tell from the photos where exactly it should be seated.

I do not have the foam blocking any portion of the intake; it seems to be seated nicely in the box.

I'm using magnets to hold the box, I installed the little rubber feet. I also made sure to get the two screws in the back of the box.

I opened and checked the shaft and from what I could see it looks ok, I did not remove the bearing, I couldn’t figure it out.

The bottom and top lids of the box don’t fit very tightly and could be adding to the sound.

Thanks!

It will probably be reduced in a week or so just from wear in of parts. The only thing I could suggest is to pry out the bush bearing, this is the collar around the hole. A slotted screwdriver can be used to remove it. Reinsert it rotated 180 degrees. It will only go in in two positions. Sometimes this helps.
