How to Prevent Plumbing Issues During the Winter

Winter brings cozy nights and festive cheer, but it also carries the threat of freezing temperatures that can wreak havoc on your home's plumbing. A burst pipe is more than just an inconvenience; it can lead to significant water damage, costly repairs, and major disruption to your life. The good news is that with a little preparation, you can protect your pipes and keep your plumbing system running smoothly all season long.

Why Winter is Tough on Your Plumbing

Understanding why winter is so problematic for plumbing is the first step toward prevention. When water freezes, it expands by about 9 percent. If water inside a pipe freezes, this expansion puts immense pressure on the pipe walls, whether they are made of metal or plastic. This pressure can easily cause a pipe to crack or burst.

Pipes most at risk are those in unheated areas of your home, such as basements, crawl spaces, attics, garages, and exterior walls. Even a small crack can release a surprising amount of water once the pipe thaws, leading to flooded basements, damaged ceilings, and ruined floors.


Insulate Your Pipes for Maximum Protection

Pipe insulation is your first and best line of defense against freezing. It's an affordable and effective way to keep your pipes from reaching freezing temperatures.


Identify At-Risk Pipes

Start by taking a tour of your home to identify pipes located in unheated or poorly insulated areas. Pay close attention to:

• Pipes in crawl spaces and attics.

• Pipes running along exterior walls.

• Plumbing in the garage, especially if it's not heated.

• Any pipes in unheated basements or cellars.


These are your primary targets for insulation. Don't forget to check under kitchen and bathroom sinks, particularly if they are on an outside wall.


Keep Your Home Warm

Maintain a consistent temperature throughout your house, day and night. If you plan to be away for an extended period during the winter, do not turn your heat completely off. Set the thermostat to at least 55°F (13°C). This small investment in heating costs is far less than the expense of repairing a burst pipe and the resulting water damage.


Winterize Your Sprinkler System

If you have an in-ground irrigation system, it needs to be properly winterized. This process, known as a "blowout," involves using an air compressor to force all the water out of the sprinkler lines. Trapped water can freeze and damage the entire system. Because this requires special equipment and can be dangerous if done incorrectly, it's often best to hire a professional irrigation specialist for the job.

Additional Winter Plumbing Tips

Seal Air Leaks

Look for air leaks around your home where cold air might be seeping in. Check for cracks and holes in your foundation, around windows and doors, and where utility lines enter the house. Use caulk or spray foam to seal these gaps. This not only helps protect your pipes but also improves your home's energy efficiency.


Know Where Your Main Water Shut-Off Valve Is

In a plumbing emergency, every second counts. You need to know the location of your home's main water shut-off valve and how to operate it. This valve controls the water supply to your entire house. In the event of a burst pipe, shutting off the water main immediately can prevent catastrophic damage. Show everyone in your household where it is and how to turn it off.
