Does this pump sound normal?

It sounds like it's excessive, but I'm new to all this and the spa is new to me.

What you are hearing is pump 1 (noisy to me)
Then pump 2 on low speed, then on high speed (all sounds normal and functions fine,, Even when it sounds like it's just humming)
Then pump 1 again.

It sounds like bearings.

Replacing bearings is not hard, it's a pain, but you can do it if mechanically inclined. Or buy a new pump (quite expensive compared to bearings). Buying a new pump would probably be cheaper than having a tech look at it / fix it. If your at least mechanically inclined enough to remove the pump, you can call around to different machine shops to see if one would replace the bearings for you. The more homework you do (manual / specification / buy parts) the cheaper the price, I would hope.

Mike,

Could be bearing also could be a fan blade scraping a housing. Both relatively easy to fix. Can you access the pump to take a look? How old is the unit? Was it recently moved?

Chris, It has not been moved recently. The unit is 8-10 years old and taking off the cover doesn't really make it clear whether it's the impeller or the motor. I see there are couplings connected. Is the next step to pull it out at the next water change? Are there bearing kits available?
