How do you make a pool pump more quiet ? Can you insulate parts ?

Pool pump motors will get noisy when the bearings start to fail. Many times they fail because the shaft seal has started to leak and gets the bearing closest to the pump to get rusty and break down. It is pretty obvious if there is some water under the pump when it is running, or if the motor has hard water builup around the end. Those bearings are about 10 - 15 bucks a piece and the seal is about 20 for a 1 hp pump anyway. It's just being able to do it yourself. Sometimes the motor bolts break off when it is disassembled. If it is much more than 2 horse power then ask your neighbor to get it repaired. If it is a small one then it is better to replace it. The cost of repairs at a pump repair shop could be close to that of replacing it.

Quiet Pool Pumps

I entered "Insulate Pool Pump" in google and it came up with a few things. One, as I suspected, was that if you enclose it there is a heat problem and it will shorten the life of the pump. It also said if there was noise because of vibrations on a cement slab, there were things you could do to stop that too. I think the main problem is that your neighbor has to be willing to make these adjustments, if not you can check your local city noise ordinances and see what can be done...but of course your neighbor will probably never talk to you again if they have to shut it down. I don't know what you can do on your side to eliminate noise other than fencing your property.

form of some sort could be used to absorb some of the sound waves, much like they use in recording studios, that should help eliminate the noise without causing overheating problems with the pump, rather than enclosing the pump. goodluck, hope this helps!

The noise is likely caused by a failed shaft bearing inside the electric motor. There is no way to make it quieter. Insulation might help, but that would also block the air flow which would cause it to overheat.

yeah his impeller is bad and or bearings are bad. My neighbor pump runs all the time and I can barley hear it. If you can hear the pump there nothing you can do. Other than while there not looking shut it off. HA
