I have a pentair superflo .75 hp. The motor is about a year old.
I've noticed it is making a kind of a continuous.. veroom...veroom...veroom...veroom... sound as it's pumping. It's not high pitched. But seems to have gotten louder in recent months.
Water is pumping fine, it primes fine, and otherwise wouldnt notice anything wrong with it. I've tried cleaning the filter, the basket, etc.
Could bearings be going bad already?
Any ideas would be helpful. Thanks.
