For normal precaution:

• Insulate exposed pipes with heat tape, newspapers, or rags;
• Place a 60-watt light bulb close to the water meter to keep it from freezing;
• If pipes are close to an exposed outside wall, open the cabinet door to let room heat in;
• Use a hair dryer or turn up the heat in your home to 75 degreex to thaw a pipe. Do not use a torch;
• If a pipe bursts, shut off the main valve, usually located near the meter;
• Be award that leaks sometimes don't show up until a pipe thaws, when they can cause extensive damage to plaster walls.

If you'll be away for the winter:

• Drain pipes completely;
• Pour a cup of antifreeze into the drain traps; toilet bowls and tanks;
• Make sure teh main shut-off valve is turned off;
• Open all faucets;
• Drain the hot water tank.
