Why Will No Pool Shops Repair My Pump Motor?
I have a 4 year old, 3hp, Pentair Whisperflo pump that is dedicated only to my infinity edge. It has worked fine up until the last time I tried to turn it on. It would hum for about 4 seconds and then trip the breaker. I checked the start capacitor. It is fine. I then took off the rear cap which exposed the motor shaft. I put a wrench on it and it is very hard to turn. I assumed it was the bearings. So, I called 6 pool shops and every single one of them told me that it would be cheaper for me to just buy a new motor! They said the labor was just too much to change out the bearings, the new bearings never last long, blah, blah, blah.
So, like most things in my life, I took it into my own hands. I tore the motor apart (never have done this before), and discovered that the front bearing is indeed seized up. It took me a whopping 15 minutes to tear it down to the point of accessing the front bearing. Next, I need to find the correct part and see what the price is. I can not believe it would cost too much. So, a couple of questions:
What would have caused this bearing to go bad so early? I have been told that this pump is a very good pump.
Why are repair shops unwilling to do this repair? Am I missing something?
Should the repair job last a long time, even though two of the shops told me it would not?
