My pump is in ok condition but it stopped working, motor is dead. Pump is old but functions, motor was replaced in 2017. I would like to change to a variable speed. What options are there based on what I currently have? Would it be a good time to replace the wetted pump components as well (i.e. seal plate, diffuser, o rings, others)? I have a salt water pool and automated via Pro-Logic.
