How to Prepare Your Plumbing for Winter: Essential Tips to Avoid Emergencies

Winter can turn small plumbing issues into full-blown emergencies overnight. A single cold snap and suddenly, pipes freeze and burst, water heaters give up, and you’re left scrambling for help.

At National Plumbing, we know how stressful and costly winter plumbing disasters can be. That’s why our licensed technicians help homeowners and small business owners prepare before the cold sets in. Let’s walk through essential steps to protect your plumbing—and your peace of mind—this winter.

Why Winter Threatens Your Plumbing ❄️

When temperatures drop, water inside your pipes can freeze. Water expands as it freezes, putting immense pressure on pipes—think of a soda can left in the freezer. Eventually, pipes can crack or burst, causing leaks, water damage, and big repair bills.

Winter also stresses water heaters and boilers, which work overtime to keep water warm. Outdoor fixtures and hoses are especially vulnerable to freezing and cracking. Even minor leaks can worsen quickly in cold weather, making emergency plumbing calls far more likely.

Pipe Insulation and Protection

Frozen pipes are one of winter’s most common plumbing emergencies. Protecting pipes is like wrapping a scarf around your neck before heading out into the cold.

Steps to insulate and protect your pipes:

• Identify exposed pipes: Focus on pipes in unheated areas—basements, crawl spaces, garages, and exterior walls.
• Use foam pipe insulation: Available at hardware stores, pipe sleeves or foam tubing fit over pipes to keep the cold out.
• Seal gaps and cracks: Use caulk or spray foam to close openings where cold air can enter near pipes.
• Let faucets drip: During extreme cold, a slow drip keeps water moving and reduces pressure buildup.
• Open cabinet doors: Allow warm air to circulate around pipes under sinks.

For added peace of mind, National Plumbing’s technicians can assess your home’s vulnerable spots and recommend the right insulation solutions.

Maintaining Water Heaters and Boilers for Winter

Your water heater is the unsung hero of winter. But when it fails, cold showers are just the start of your troubles.

Here’s how to keep your water heater and boiler in shape:

• Drain sediment: Sediment buildup reduces efficiency and can cause overheating. Flush your water heater at least once a year.
• Check the temperature: Set water heaters to 120°F (per U.S. Department of Energy guidelines) to balance comfort and safety.
• Inspect for leaks: Small drips can signal bigger problems. Look for corrosion, rust, or pooling water.
• Test the pressure relief valve: Lift the lever—water should flow out and stop when released.
• Schedule a professional inspection: Licensed plumbers can spot early warning signs and perform safety checks.

Boilers should be inspected annually by qualified technicians to ensure safe, efficient operation. Don’t wait for a breakdown to find out something’s wrong.

Winterizing Outdoor Plumbing Fixtures

Outdoor plumbing is especially at risk during winter. A frozen hose bib can send water pouring into your walls or basement.

Winterizing steps:

• Disconnect and drain hoses: Remove garden hoses and drain any remaining water.
• Shut off outdoor water supply: Use the shut-off valve inside your home, then open the outdoor faucet to drain.
• Install insulated covers: Faucet covers help shield outdoor spigots from freezing temperatures.
• Check irrigation systems: Blow out sprinkler lines or have a professional winterize them.

These simple steps can prevent costly repairs and keep your outdoor plumbing safe until spring.

Emergency Steps if Plumbing Freezes 🚨

Sometimes, even the best preparations aren’t enough. If you turn on a faucet and only a trickle comes out, you might have a frozen pipe.

What to do:

• Turn off the main water supply: This prevents flooding if the pipe bursts.
• Open faucets: Relieve pressure and allow water to escape as the pipe thaws.
• Apply gentle heat: Use a hair dryer, heating pad, or warm towels—never an open flame.
• Call National Plumbing: If you can’t locate or thaw the pipe, or if you spot leaks, get professional help right away.

Acting quickly can minimize damage and keep repair costs down.

Costs & Time Factors

Winter plumbing prep doesn’t have to break the bank. Most pipe insulation and fixture winterizing can be done in an afternoon with affordable materials.

Typical time and cost ranges:

• DIY pipe insulation: 1–2 hours, modest material cost
• Professional inspection: 1–2 hours, varies by home size and complexity
• Water heater maintenance: 1 hour, plus parts if needed

Investing a little time now can save you from expensive water damage and emergency plumbing bills later.

When It’s an Emergency

Some situations can’t wait. Call for emergency plumbing help if you notice:

Delaying repairs can lead to bigger problems and higher costs. National Plumbing is available around the clock for urgent needs.

FAQ: Winter Plumbing Prep

How can I tell if my pipes are at risk of freezing?
Pipes in unheated spaces or along exterior walls are most vulnerable. If you’ve had frozen pipes before, take extra precautions.

Is it safe to use a space heater to thaw pipes?
Only use safe, indirect heat (like a hair dryer or heating pad). Never use open flames or torches, which can cause fires.

How often should I service my water heater or boiler?
At least once a year—preferably before winter. Regular maintenance extends equipment life and catches issues early.

Can I use antifreeze in my plumbing?
Never use automotive antifreeze in drinking water lines. For seasonal homes, plumbers use special products for winterization.

Special Considerations for Winter Plumbing

• Older homes: May have less insulation and more vulnerable pipes.
• Businesses: Frozen pipes can shut down operations—schedule inspections before winter hits.
• Sump pumps: Test before heavy snow or rain; a failed pump can lead to basement flooding.
• Water filtration systems: Ensure filters are protected from freezing.

National Plumbing’s licensed technicians are trained to spot unique risks and recommend tailored solutions for every property.
