I have a 3 year old proline cartridge filter with a 2 hp pump for my 30 round above ground pool. Just fired it up for the first time this season and the pump sounds weird. Like there is something in the fan or maybe bearings going.
are there any common pump problems that are easily repaired by a novice.? what should I look at or try aside from going out and buying a new pump.
Its still working by the way it just sounds awful.
