Good luck with the fix/ replacement! Let us know if you need any advice

Preventing it from happening again depends on what the original problem was. If it was the shaft seal, just periodicly check for drips under the pump - if you see some one of the seals needs to be replaced before the leak can do damage. If it's slight corrosion freezing things up, try to keep the motor as dry as possible and treat the connections with an approved rust inhibitor. Avoid splashing chemical leaden pool water on the pumps. Finally, hope for a better pump this time
