Preparing your Water Pipes for Winter
Extreme Weather Conditions: 
• A trickle of hot and cold  water might be all it takes to keep your pipes from freezing. Let warm water drip overnight, preferably from a faucet on an outside wall. 
Before You Leave
• Set the thermostat in your house no lower than 55°F (12°C).

What do you do if your pipes freeze?
• You may be able to thaw a frozen pipe with the warm air from a hair dryer. Start by warming the pipe as close to the faucet as possible, working toward the coldest section of pipe.

PWSD No. 3 is asking for your assistance by completing a short questionnaire.
