"As night time temperatures dip near freezing across much of Western Washington, utility officials are warning residents to take the following steps to guard against costly damage to their home's plumbing:
• When you are away — if you have power — make sure the heat is set no lower than 55 degrees.
• When the temperature dips below freezing, open indoor faucets and run a small trickle of water to help keep your water pipes from freezing. The cost of running extra water will be much less than the cost of repairing broken pipes.
• Open cabinet doors below sinks so warm air can circulate around the pipes during extremely cold weather.
• Open doors to cabinets located on exterior walls to expose water pipes to warmer room temperatures.
• If possible, shut off the water to outside faucets.
• Install insulated covers on all outside water faucets.
• Cover all exposed pipes with insulation material.
• Shut off water service to vacant homes if the heat can't be kept on. "
