Frozen pipes are one of the most distressing problems a homeowner can encounter. Whether you're in the northern states where deep freezes are common or in southern regions where sudden cold snaps can catch homes unprepared, the risk is real. Here's how to prevent pipes from freezing and what to do if they do.
When water freezes inside pipes, it expands and can crack copper tubing or other materials. This can lead to a complete loss of water supply and, once the ice thaws, serious leaks or worse.
How to Prevent Pipes from Freezing
Prevention is key, especially in areas where homes may not be built for cold weather. Consider the following:
• Keep water-supply piping away from outside walls whenever possible.
• If pipes must be located on an exterior wall, insulate them well. Pipe insulation is available in rubber and fiberglass.
• Insulate pipes in unheated areas such as crawl spaces, basements, attics, and garages. Seal drafts near cables, vents, windows, and other openings.
• Before winter, shut off the water valve that supplies outdoor spigots, then drain the lines by opening each spigot until it stops dripping. Close the spigot afterward.
How to Protect Pipes During Subfreezing Temperatures
Even in southern states, a sudden drop in temperature can cause pipes to freeze. Be prepared:
• Keep garage and exterior doors closed and seal any drafts.
• Let faucets trickle - both hot and cold - to keep water moving and reduce the chance of freezing.
• Maintain indoor temperatures at 55°F (13°C) or higher, day and night. If your home is poorly insulated, consider setting it even higher.
• Keep interior doors open to allow warm air to circulate throughout the house.
• Open cabinet doors under sinks to let warm air reach the plumbing. (Keep hazardous items out of reach of children and pets.)
Check your local forecast regularly. Even if freezing temperatures are rare in your area, a single cold night can cause costly damage.
