A frozen lid should be left alone. Make sure utilities are in good working order. Leave a faucet dripping. Circulating water won't freeze in the meter or pipes. Open cabinet doors below sinks located against an outside wall.
Pipes are less likely to freeze if they're exposed to warm air.
Winterize outdoor lines. Drain water lines to outdoor faucets and disconnect garden hoses from faucets to avoid freeze-ups. Locate the water shut-of valve. Before a pipe breaks is the time to locate the shut-off valve and learn how to turn it off. Educate your family.
