Last year I replaced the motor on my Hayward SuperPump after only three seasons of use. This year, after only one season, a bearing has already gone out due to a failed seal.
A local motor shop (that services pumps/motors for most of the local pool installers) said that recently they have seen a large number of motor failures with pumps used in saltwater pools. He installed a newly designed seal that is supposed to hold up better in saltwater service.
He also mentioned a "disc" of some type, that you place in the strainer/basket, that is supposed to help reduce the effects of the saltwater before it enters the pump. I have searched for such an item, but, nothing comes up. Does anyone here know what he might be talking about?
I can't afford to be servicing my motor every season.
