I live in Atlanta, I have a salt-water pool, and my motor just today started to make a louder than normal sound. The motor is under warranty but the pool service can't get out until Tuesday. Temperatures are currently around 30 and will be closer to 20 tonight. It will warm into the 40s this weekend but still fall below freezing at night. I believe the noise may be due to worn bearings but not certain (I am no expert!). How long does it normally take for the motor to go in this situation, and can I wait until Tuesday? How long would it take for the pipes to freeze if the motor stops working?
