I have a Jandy Pro Series Plus HP 1.5 in a fairly new pool (3.1 years old) that is failing. It has a very loud whining sound. It is just a bit out of warranty, and my inclination is just to replace it myself, rather than go through the whole process with a pool company evaluating and replacing/repairing. My pool is 45,000 gallons with no water features. What would be a reasonable way to go with this as far as a compatible pump? Is there a benefit to a VS in my situation?
