How to Prevent Frozen Pipes in Lawrenceville

Lawrenceville residents know that Georgia winters can be unpredictable. We might enjoy 60-degree days in January, only to face a sudden cold snap that sends temperatures plummeting into the teens. These rapid temperature changes are particularly dangerous for plumbing systems that are not prepared for freezing conditions. A burst pipe can cause thousands of dollars in water damage, but with proper prevention, you can protect your home.

Understanding Why Pipes Freeze

Water expands when it freezes, and this expansion creates tremendous pressure inside pipes. That pressure does not need to freeze the entire pipe; even a small ice blockage can create enough pressure to crack or burst pipes elsewhere in your plumbing system. Pipes most vulnerable to freezing include those in unheated interior spaces like basements, crawl spaces, attics, and garages, as well as pipes running through exterior walls with little or no insulation.

In Lawrenceville, many homes have crawl spaces rather than full basements. These crawl spaces can get surprisingly cold during hard freezes, making the pipes running beneath your home particularly vulnerable. If your home was built with pipes in exterior walls, these too are at risk during extended cold periods.

Insulate Exposed Pipes

The most effective prevention measure is insulating pipes that are exposed to cold air. Pipe insulation is inexpensive and available at any hardware store. Focus on these areas:

• Crawl space pipes: These are often the most vulnerable. Use foam pipe sleeves or fiberglass wrap to insulate all water lines in your crawl space.
• Attic pipes: Even in Georgia, attics can reach freezing temperatures on cold nights. Insulate any water lines running through attic spaces.
• Garage pipes: If you have plumbing in an unheated garage, insulate these pipes and consider keeping the garage door closed during cold snaps.
• Exterior wall pipes: While harder to access, pipes inside exterior walls can benefit from added insulation blown into wall cavities.

For added protection, consider heat tape or heat cable for pipes in extremely vulnerable locations. These electrically powered products provide gentle heat to prevent freezing during the coldest weather.

The Drip Method

When temperatures are expected to drop below freezing, letting your faucets drip is one of the simplest and most effective preventive measures. Moving water is much more difficult to freeze than standing water, and even a small trickle can prevent ice from forming inside pipes.

Focus on faucets served by pipes that run through exterior walls or unheated spaces. Let both the hot and cold lines drip slightly; even hot water lines can freeze if not used overnight. The cost of the extra water usage is minimal compared to the cost of repairing a burst pipe.

Open Cabinet Doors

Kitchen and bathroom cabinets located against exterior walls can trap cold air around pipes. During freezing weather, open these cabinet doors to allow warm air from your home to circulate around the plumbing. This is especially important for cabinets housing kitchen sinks and bathroom vanities on exterior walls.

If you have children or pets, remember to move any cleaning chemicals or other hazardous materials out of reach when opening lower cabinets.

Protect Outdoor Faucets

Outdoor faucets, also called hose bibs or spigots, are extremely vulnerable to freezing. Take these steps to protect them:

• Disconnect garden hoses: Water trapped in hoses can freeze and back up into the faucet and pipe. Remove all hoses before winter arrives.
• Drain outdoor water lines: If you have shut-off valves for outdoor faucets inside your home, turn them off and open the outdoor faucet to drain remaining water.
• Install faucet covers: Inexpensive foam faucet covers provide insulation for outdoor spigots during cold weather.
• Consider frost-free faucets: If you are replacing outdoor faucets, frost-free models extend the shut-off valve further into the heated portion of your home.

Maintain Consistent Indoor Temperature

While it is tempting to lower your thermostat at night or when away to save energy, very low indoor temperatures put your pipes at risk. Keep your thermostat set to at least 55°F, even when you are away from home. The money saved on heating is insignificant compared to the cost of water damage from a burst pipe.

If you are leaving town during winter, ask a neighbor or friend to check on your home daily and ensure the heating system is working properly.

What to Do If Your Pipes Freeze

If you turn on a faucet and only a trickle comes out, suspect a frozen pipe. Take these steps immediately:

1. Keep the faucet open: As you treat the frozen pipe, the running water will help melt the ice.
2. Apply heat to the pipe: Use a hair dryer, heating pad, or towels soaked in hot water. Start near the faucet and work toward the coldest section.
3. Never use open flame: Do not use blowtorches, propane heaters, or other open-flame devices. They are fire hazards and can damage pipes.
4. Check all faucets: If one pipe is frozen, others may be too.
5. Call a professional if needed: If you cannot locate or access the frozen pipe, or if a pipe has burst, contact us for emergency burst pipe repair.

By taking preventive action before cold weather arrives, you can protect your Lawrenceville home from the damage and expense of frozen pipes. However, if you do experience a pipe freeze or burst, Pro Plumber Lawrenceville is available 24/7 for emergency service.
