All of our pool equipment is a quality, known brand name except for the pump. There, we somehow ended up with an off brand called 'Roaring River' (made in China). The pump has always been loud, but now is getting louder and louder. The noise is coming from the motor, not the pump itself. I pulled the motor off and found there is a small amount of play in the shaft and it turns relatively smoothly, but not perfectly smoothly. That said, I'm sure the bearings are about shot.
I can't find this brand anywhere on the internet. Has anyone ever heard of it or know where I can cross reference bearing sizes for it?
