Why is my pump noisy?

Why is my pump noisy?
Update Time:2015-07-30
Themotor has an internal cooling fan that can be heard. When installing your pump,it is advised to carefully consider the location; under a bedroom window maynot be an ideal location.

Vibrationfrom the pump’s feet and the base (where the pump rests) can cause the pump tobe noisy. A piece of old carpet or rubber between the pump’s base and equipmentpad might reduce the noise.

Ensurethe pump is level and the suction lines are not higher then the pump.

Thebearing(s) might be noisy due to age or high concentrations of chemicals andheat. A leaky pump seal could damage the front motor bearing. It is veryimportant to quickly repair any leaks around the pump to prevent extensivedamage. It is recommended that you replace the bearings or the entire motor.Contact an Authorized Pool/Spa Professional orDealer for repair.

Manytimes a noisy pump can come from cavitations (starving the pump). Cavitationshave two possible causes, which are both hydraulically (water flow) related.The first is that the suction piping is undersized. If this pipe is undersized,the amount of water the pump requires to operate properly is reduced.Increasing the pipe size (increase water flow) or dropping the size of theimpeller (decrease water flow) can quiet the pump. The second is that there islittle or no backpressure on the pressure side of system (water feature pumpsare a good example). Adding a valve or something to increase backpressure isadvised.

For all of the above, it may be necessary to contact anauthorized pool/spa professional or dealer for assistance.
