Replace pool pump

For the past 16 years, I have to replace my pool pump every 2 to 3 years.  It only runs about 6 to 8 hours a day or less.  Why do I have to keep relacing this pump?  It is a Pentair 1.5 motor if this helps.

Hello Chris - We’d be glad to assist you. What type of motor failure are you having? Is it getting really loud before it stops working?
