When temperatures are consistently at or below freezing:

• If you have pipes that are vulnerable to freezing, turn water off at the source and empty the pipes of residual water.
• Open cabinet doors to expose pipes to warmer room temperatures to help keep them from freezing.

If your pipes freeze:

• Shut off the water immediately. Don't attempt to thaw frozen pipes unless the water is shut off. Freezing can often cause unseen cracks in pipes or joints.
• Apply heat to the frozen pipe by warming the air around it, or by applying heat directly to a pipe. You can use a hair dryer, space heater or hot water. Be sure not to leave space heaters unattended, and avoid the use of kerosene heaters or open flames.
• Once the pipes have thawed, turn the water back on slowly and check for cracks and leaks.
