As winter approaches, it’s essential to winterize your plumbing to prevent frozen pipes, water damage, and costly repairs. When water freezes inside pipes, it expands, increasing pressure and potentially causing them to burst. This can lead to severe structural damage and expensive emergency repairs, making proper winterization a necessity rather than an option.

At Breakwater Plumbing, we understand the importance of taking proactive steps to winterize your plumbing before temperatures drop. Our expert team is here to help homeowners and businesses protect their plumbing systems from the harsh effects of winter. By following these proven winterization tips, you can prevent freezing, ensure efficient water flow, and keep your plumbing in top condition throughout the colder months.

1. Insulate Your Pipes

Why Pipe Insulation is Essential

Pipes in unheated areas such as basements, crawl spaces, garages, attics, and exterior walls are at the greatest risk of freezing. If these pipes are not properly insulated, the cold air around them can quickly drop the water temperature inside, leading to blockages and possible bursts. Insulating your pipes adds an extra layer of protection, reducing heat loss and maintaining a consistent temperature.

Best Pipe Insulation Materials

• Foam Pipe Sleeves – These are one of the most common and affordable insulation materials. They are easy to install and provide effective insulation for pipes in moderate winter conditions.
• Fiberglass Wrap – This is ideal for extremely cold environments, as it provides a higher level of insulation than foam sleeves. However, fiberglass must be handled carefully due to its fine particles, which can irritate the skin.
• Heat Tape or Heat Cables – For pipes that have a history of freezing, electric heat tape or heat cables can be applied to provide direct warmth. These are particularly useful for pipes in garages, attics, and basements where ambient temperatures are lower.

How to Properly Insulate Pipes

1. Identify vulnerable pipes – Locate exposed pipes in areas prone to freezing.
2. Measure the length of the pipe – Ensure that you cut the insulation material to the correct size.
3. Wrap or slide the insulation – If using foam sleeves, simply snap them over the pipe. If using fiberglass wrap, secure it with duct tape.
4. Secure insulation – Use zip ties or strong tape to hold the insulation in place, ensuring there are no gaps.
5. For extreme cold, consider applying heat tape first, then covering it with insulation for extra protection.

2. Drain Outdoor Faucets and Sprinkler Systems

Why It’s Necessary

Outdoor plumbing is highly exposed to harsh winter conditions, making it one of the first areas in a home’s plumbing system to freeze. If water remains inside outdoor faucets, hoses, or sprinkler systems, it can expand when frozen, leading to cracked pipes and leaks once temperatures rise.

Steps to Protect Outdoor Plumbing

1. Disconnect and drain garden hoses – Leaving hoses connected traps water inside the pipe, which can freeze and cause damage.
2. Turn off the outdoor water supply – If your home has a dedicated shutoff valve for exterior plumbing, turn it off before temperatures drop.
3. Open outdoor faucets – Once the water supply is shut off, opening the faucets allows any remaining water to drain out completely.
4. Use faucet covers – These insulated covers help protect outdoor spigots from freezing temperatures and wind chill.
5. Winterize your sprinkler system – If you have an irrigation system, the best method to prevent damage is to blow out the lines using compressed air, removing any residual water.

3. Maintain a Warm Temperature Indoors

Why Indoor Pipes Can Freeze

Even indoor plumbing is vulnerable if it is located near exterior walls, crawl spaces, or unheated basements. Pipes can freeze overnight, leading to potential bursts and costly repairs.

How to Prevent Indoor Pipes from Freezing

• Keep cabinet doors open – This allows warm air to circulate around pipes beneath sinks, reducing the chances of freezing.
• Maintain an indoor temperature of at least 55°F (13°C) – Even if you are away from home, never turn your thermostat lower than this level.
• Seal any cracks or openings – Cold air can seep in through gaps in walls, floors, or foundations, lowering the temperature around pipes. Use caulking, foam insulation, or weather stripping to block drafts.

Using Additional Heating Sources

• Portable heaters – If certain areas of your home, such as the basement or garage, tend to be colder, use space heaters to keep pipes above freezing temperatures.
• Heat tape – Self-regulating heat cables wrap around pipes and provide consistent warmth to prevent freezing. These can be plugged into an outlet and left on during cold spells.

4. Let Faucets Drip During Extreme Cold

How Running Water Prevents Freezing

A slow, steady trickle of water keeps pipes from freezing because moving water is less likely to freeze than stagnant water. This method is particularly useful for:

• Homes with a history of frozen pipes
• Properties in extremely cold climates
• Exposed pipes in unheated areas

Best Practices for Dripping Faucets

• Allow both hot and cold water to trickle from each affected faucet.
• Focus on faucets connected to exterior walls or in unheated sections of the home.
• If temperatures drop below 20°F (-6°C), keeping a slow drip running is strongly recommended.

5. Locate and Test Your Main Water Shutoff Valve

Why It’s Important

In case of a pipe burst, quickly shutting off the main water supply can prevent severe flooding and damage.

How to Locate Your Main Shutoff Valve

• Usually found near the water meter, in a basement, crawl space, or utility room.
• In colder climates, the valve is typically located inside the home to prevent freezing.

How to Shut Off Water in an Emergency

1. Turn the valve clockwise (to the right) to stop water flow.
2. Drain remaining water by opening faucets.
3. Call a professional plumber immediately if a pipe has burst.

6. Service Your Water Heater

Why Water Heater Maintenance is Crucial in Winter

During winter, your water heater works harder to provide hot water, increasing wear and tear. A malfunctioning heater can leave you without hot water when you need it most.

Winter Water Heater Maintenance Tips

• Flush the tank to remove sediment buildup that reduces efficiency.
• Check the temperature setting – Keep it at 120°F (49°C) for optimal performance.
• Inspect for leaks or corrosion to catch issues early.
• Consider insulating the tank with a water heater blanket to reduce heat loss and save energy.

7. Preparing for Extended Winter Vacations

If you’re leaving home for an extended period during the winter, taking the right steps to winterize your plumbing is essential to prevent frozen pipes and costly water damage. Without proper precautions, prolonged exposure to freezing temperatures can lead to burst pipes, leaks, and significant repairs upon your return.

Turn Off the Main Water Supply and Drain Pipes

One of the best ways to winterize your plumbing before a trip is to shut off the main water supply. This eliminates the risk of leaks or pipe bursts while you’re away. After turning off the valve, open all faucets to drain any remaining water, reducing the chances of freezing.

Set Your Thermostat to a Safe Temperature

To further winterize your plumbing, keep your home’s thermostat at 55°F (13°C) or higher. Even if no one is home, maintaining a stable indoor temperature prevents interior pipes from freezing. Opening cabinet doors under sinks will also allow warm air to circulate around exposed pipes.

Shut Off and Drain Your Water Heater

If the water supply is turned off, shutting down the water heater helps prevent pressure buildup and overheating. To properly winterize your plumbing system, set the water heater to vacation mode (if available) or turn off the gas/electric supply to reduce energy consumption.

Insulate and Protect Pipes in Vulnerable Areas

Pipes located in attics, crawl spaces, basements, and garages should be insulated with foam sleeves or fiberglass wrap to prevent freezing. Outdoor faucets should be covered with insulated faucet protectors to add an extra layer of protection.

Have Someone Check Your Home

If possible, ask a neighbor or friend to check on your home periodically while you’re away. They can ensure that your heating system is working, inspect for leaks, and, if necessary, let faucets drip slightly to winterize your plumbing against unexpected temperature drops.

Taking these essential precautions to winterize your plumbing before leaving for an extended period will help prevent costly repairs and give you peace of mind while traveling.

8. What to Do If Your Pipes Freeze

Signs of Frozen Pipes

• No running water from the faucet.
• Frost forming on exposed pipes.
• Unusual noises, such as banging or gurgling, when turning on faucets.

How to Thaw Frozen Pipes Safely

1. Open the affected faucet to relieve pressure.
2. Apply gentle heat using a hairdryer, heating pad, or warm towels.
3. Never use an open flame or high-powered heat sources, as these can damage pipes or cause fires.
4. Check for leaks – If a pipe has burst, shut off the main water supply immediately and call a professional plumber.
