Our Hayward SP2602VSP has started making some loud noises (whining?) after 2 years of continuous lowspeed (1000rpm) use. We have recently converted to salt water and did not know we should have installed a salt water kit for the bearing seal. As we seem to need a new motor, what options do we have? We like to run the pump 24/7 on the lowest speed necessary to provide flow for the aquarite clorine generator only using a higher speed to clean the pool 3 times per week. Thanks in advance for the help.
