My first post...my apologies if I leave out necessary details, overlooked post requirements or posted in the wrong forum.
I have a 1HP Hayward Super II Pump that is going on 8 yrs old this fall. It has been working well without any major issues, however every year it seems to get louder and louder. It is not a high pitch squeal, rattle or a hum, rather (for lack of a better way to explain) it makes a rhythmic 'wuhh, wuhh, wuhh, wuhh...'. The pool equipment is on the same side of the house as our master bedroom on the 2nd floor, and it's getting loud enough that it can keep you awake at night. We do not have a timer on the pump, and used to have a UV sanitation system which required the pump to operate 24/7. We have since switched to a salt chlorinator so I suppose I could run the pump only during the day, but without a timer I would not really enjoy turning it on and off manually every day.
One 'off the cuff' opinion I received was to replace the bearings, but after doing my own research it seems like this wouldn't help.
Any one have any thoughts on what could be causing it to run so loudly?
