Why Is My Pump Running Loud?

The bearings may be noisy due to normal wear.  Feeding high concentrations of chemicals through the skimmer will cause corrosive damage to the seal.  This can cause a leak and damage the motor bearings.

Generally if this is happening you will see water pooling just underneath the motor.  You do not need a new pump per se.  Just bring it in and we will let you know what is going on with your pump. Chances are you just need the seal and bearings changed.
