I have a Pacfab Whisperflo 1 HP pump that is getting loud. The pump was abused last summer and I was wondering if it can be fixed or it should be replaced.

The pump was turned on and left unattended for may hours. The valve that controls the automatic cleaner and the return jets was in the off position. So there was no were for the water to go. The pump must have gotten extremely hot causing the pcv outlet fitting (the one on top of the pump) to push out and disconnect. This caused the pool to drain below the skimmer and then the pump continued to run dry.

I replaced the pvc fitting and to my surprise the pump works but is much louder. I have a feeling its only a matter of time before it dies. Can I repair it or should I just buy a new pump.
