How to Prevent Frozen Pipes in North Alabama

Hard freezes are not common in Madison, but when temperatures drop into the teens, burst pipes follow. Homes here are not built for sustained cold the way homes up north are: pipes run through garages, exterior walls, attics, and crawlspaces with little insulation. A few simple steps prevent most of the damage.

Before Winter

• Insulate exposed pipes in garages, crawlspaces, attics, and under sinks on exterior walls. Foam sleeves are inexpensive and easy to install.
• Disconnect garden hoses and cover outdoor spigots with insulated covers.
• Shut off and drain irrigation systems and backflow preventers.
• Seal gaps where cold air reaches pipes, like crawlspace vents and wall penetrations.
• Find your main shut-off and make sure it works.

When a Hard Freeze Is Forecast

• Let faucets on exterior walls drip, both hot and cold
• Open cabinet doors under sinks to let warm air reach pipes
• Keep the garage door closed
• Keep the thermostat at 55°F or higher, even if you leave town
• Consider heat tape for pipes that froze before

If a Pipe Freezes

If a faucet only trickles during a freeze, the line is likely frozen. Leave the faucet open and warm the pipe gently with a hair dryer or space heater, starting near the faucet and working back. Never use an open flame. If you cannot find the frozen section, or the pipe has split, shut off the main water and call a plumber.

After the Freeze

Pipes often leak once they thaw. Check garages, crawlspaces, and ceilings below upstairs bathrooms, and watch your water meter for movement. If a pipe burst, follow what to do when a pipe bursts.
