Don’t Let Winter Catch You Off Guard: Your Complete Guide to Insulating Outdoor Plumbing

As the crisp fall air arrives and temperatures begin to drop, it’s time to start thinking about protecting your home’s outdoor plumbing. At Struse Plumbing & Air, we see countless emergency calls each winter from homeowners dealing with burst pipes and water damage—problems that could have been easily prevented with proper fall preparation.

The good news? Winterizing your outdoor plumbing is straightforward, and taking action now can save you thousands of dollars in repairs and the headache of dealing with frozen pipes during the coldest months of the year.

Why Outdoor Plumbing Insulation Matters

When water freezes, it expands by approximately 9%. This expansion creates tremendous pressure inside your pipes—up to 2,000 pounds per square inch. Even the strongest pipes can’t withstand this force, leading to cracks, splits, or complete ruptures.

The Real Cost of Frozen Pipes:

A single burst pipe can cause extensive water damage to your home, potentially costing $5,000 to $10,000 or more in repairs. Beyond the financial impact, you’ll deal with disrupted water service, potential mold growth, and the stress of major home repairs during the holiday season.

The exposed nature of outdoor plumbing makes it especially vulnerable. Unlike indoor pipes that benefit from your home’s heating, outdoor fixtures face the full brunt of winter weather.

Which Outdoor Plumbing Needs Protection?

Before you begin winterizing, identify all the outdoor plumbing that requires attention:

Exterior Fixtures:

• Outdoor faucets and hose bibs
• Sprinkler system components
• Pool and hot tub plumbing
• Outdoor showers
• Garden irrigation lines

Exposed Pipes:

• Pipes in unheated garages
• Plumbing in crawl spaces or basements along exterior walls
• Water supply lines to detached buildings
• Well pump connections

Your Step-by-Step Winterization Checklist

1. Disconnect and Drain Garden Hoses

When: Before the first hard freeze (typically mid-to-late fall)

Remove all garden hoses from outdoor faucets and drain them completely. Store hoses in a garage or shed. Even a small amount of water left in a connected hose can freeze, back up into your pipes, and cause damage to the faucet and connected plumbing.

2. Shut Off and Drain Outdoor Faucets

For Standard Outdoor Faucets:

• Locate the shutoff valve inside your home that controls each outdoor faucet
• Turn the valve clockwise to close it
• Go outside and open the faucet to allow any remaining water to drain out
• Leave the outdoor faucet open all winter to prevent pressure buildup

For Frost-Free Faucets: Even “frost-free” faucets need attention. Ensure any connected hoses are removed, and open the faucet briefly to verify proper drainage.

3. Insulate Outdoor Faucets and Pipes

Faucet Covers: Install foam faucet covers over all exterior spigots. These inexpensive covers (available at any hardware store) provide an insulating air pocket that protects the faucet from freezing temperatures. Make sure covers fit snugly and are secured properly.

Pipe Insulation: For exposed pipes, use foam pipe insulation sleeves:

• Measure the length and diameter of pipes needing insulation
• Purchase appropriately sized foam sleeves
• Slice open the sleeve and wrap it around the pipe
• Secure with zip ties or weatherproof tape
• Pay special attention to pipes on exterior walls or in unheated areas

For areas where pipes might be exposed to extreme cold or wind, consider adding heat tape beneath the insulation for extra protection.

4. Winterize Your Sprinkler System

Your irrigation system requires special attention:

Professional Blowout: The most reliable method is hiring a professional (like Struse Plumbing & Air) to perform a compressed air blowout of your system. This ensures all water is completely removed from lines, valves, and sprinkler heads.

DIY Manual Drain: If your system has manual drain valves, you can:

• Turn off the water supply to the system
• Open all manual drain valves
• Open sprinkler heads at the system’s highest and lowest points to ensure complete drainage

Controller Settings: Switch your irrigation controller to “rain mode” or turn it off completely, but don’t erase your programming for spring.

5. Protect Pipes in Vulnerable Areas

Crawl Spaces and Basements:

• Ensure crawl space vents are open during warm weather but can be closed during extreme cold
• Add extra insulation around pipes near exterior walls
• Check for drafts and seal any air leaks

Unheated Garages: If you have plumbing running through an unheated garage, insulate these pipes thoroughly and consider installing heat tape for added protection during severe cold snaps.

When to Use Heat Tape

For pipes in extremely vulnerable locations, heat tape (also called heat cable) provides active protection:

• Best for pipes that can’t be easily drained or insulated
• Must be installed according to manufacturer instructions
• Should never overlap itself
• Works best when covered with pipe insulation
• Should be inspected annually for damage

Important: Only use heat tape specifically designed for plumbing applications, and always follow electrical safety guidelines.

Advanced Protection: Insulating Outdoor Faucet Boxes

For added security, consider installing an insulated faucet box around exterior spigots. These boxes provide superior protection compared to simple covers and are especially valuable for exposed pipes that extend through exterior walls.

Don’t Forget About These Often-Overlooked Areas

Outdoor Kitchens: If you have an outdoor kitchen, ensure all plumbing is properly winterized, including sinks, refrigerator water lines, and ice makers.

Pet Washing Stations: Drain and insulate these outdoor fixtures just like regular faucets.

Decorative Water Features: Drain fountains, ponds, and other water features completely. Remove pumps and store them indoors if possible.

Signs Your Outdoor Plumbing Needs Professional Attention

While many winterization tasks are DIY-friendly, some situations call for professional expertise:

• You’re unsure how to locate shutoff valves
• Your home has complex outdoor plumbing systems
• You’ve experienced frozen pipes in previous winters
• Pipes are difficult to access or require special tools
• You want peace of mind with a professional inspection

Emergency Preparation: What If Pipes Do Freeze?

Despite your best efforts, unexpected cold snaps can still cause problems. Here’s what to do:

If a pipe freezes but hasn’t burst:

• Open the affected faucet to allow water to flow once thawed
• Apply gentle heat to the frozen section using a hair dryer or heating pad
• Never use open flames, propane torches, or high-heat devices
• Work from the faucet toward the frozen area

If a pipe bursts:

• Shut off the main water supply immediately
• Call Struse Plumbing & Air for emergency service
• Remove standing water to prevent additional damage
• Document damage for insurance purposes

Timing Is Everything

The key to effective winterization is timing. Don’t wait until after the first freeze—temperatures can drop unexpectedly, and you might not get another chance before damage occurs.

Ideal Timeline:

• Early Fall: Begin inspecting outdoor plumbing and gathering materials
• Mid-to-Late Fall: Complete winterization before nighttime temperatures consistently drop below 32°F
• Before Vacation: Always winterize outdoor plumbing before extended absences during cold weather
