Does this sound right?

I'm just trying to be careful & need opinion please.
I cleaned my 2 6101 pumps with vinegar.

When I mounted this back, I noticed some buzzing sound / vibration. I made sure there was no calcium build up & then replaced impeller on one of them & there is still buzzing sound. My wife said this sound was there for a couple of weeks now.

I'm just trying to be careful & can't take a chance with pump failure in stocked setup.

I could barely hear anything on the audio file, I would make sure the bush bearing is fully inserted and that the red oring is underneath the upper bearing and not on top and that this surface is clean. It is also important that the center hole of the propeller magnet is clean as this is where water enters to lubricate the pump. I wouldn't be overly concerned as there will always be some noise and the linked file unless it is really underrepresenting the noise present did not sound abnormal.

Thanks, I'll try it out. By the way that was recorded using my IPhone. So it is as good a recorder as it is a camera.
