Wisconsin winters are known for frigid temperatures, heavy snowfall, and icy conditions. While you may be prepared to bundle up and protect your home from the cold, your plumbing system also needs attention when temperatures drop.
Freezing temperatures can put significant stress on your pipes, fixtures, water heater, and other plumbing components. Understanding how winter weather affects your plumbing can help you prevent costly damage and keep your home running smoothly throughout the season.
Why Freezing Temperatures Are Hard on Plumbing
Water expands when it freezes. When water inside a pipe freezes, it can create pressure between the ice blockage and the closed sections of the pipe. As that pressure increases, the pipe can crack or burst.
The pipe itself does not always break at the exact location where the ice forms. Pressure can build up throughout the plumbing system, meaning a small frozen section can eventually lead to a significant leak once the ice begins to thaw.
In Wisconsin, this is especially concerning during extended periods of below-freezing temperatures.
Pipes in Unheated Areas Are Most Vulnerable
Not every pipe in your home faces the same risk. Plumbing located in areas exposed to cold air is more likely to freeze, including:
- Exterior walls
- Unheated basements
- Crawl spaces
- Garages
- Attics
- Under sinks near exterior walls
- Outdoor hose connections
Poor insulation can make these areas even more susceptible to freezing. Pipes that run through these spaces may need additional insulation or other preventative measures before winter arrives.
Frozen Pipes Can Lead to Major Water Damage
A frozen pipe may not seem like an immediate emergency if water has stopped flowing. However, the real problem can occur when temperatures rise and the ice begins to melt.
A pipe that has cracked under pressure can suddenly release water once it thaws. Depending on where the pipe is located, this can result in water damage to walls, ceilings, floors, insulation, cabinets, and personal belongings.
A small plumbing issue can quickly become an expensive repair if it goes unnoticed.
Your Water Heater Works Harder in Winter
Cold weather can also affect your water heater. During the winter, the water entering your home is colder than it is during warmer months. As a result, your water heater may need to work harder and longer to bring incoming water up to the desired temperature.
If your water heater is older or already experiencing problems, winter can make those issues more noticeable. Inconsistent water temperatures, unusual noises, leaks, or a lack of hot water are all reasons to have your system inspected.
Outdoor Plumbing Needs Winter Protection
Outdoor faucets and hose connections are particularly vulnerable to freezing temperatures. Even when a faucet is turned off, water can remain inside the connected plumbing.
Before winter sets in, disconnect garden hoses and make sure exterior faucets are properly drained. If your home has frost-free hose bibs, they should still be maintained properly to reduce the risk of freezing and damage.
Outdoor plumbing that is not properly winterized can allow freezing water to reach interior plumbing and potentially cause a burst pipe.
Signs You May Have a Frozen Pipe
Knowing the warning signs can help you address a frozen pipe before it becomes a major problem. Watch for:
- Little or no water coming from a faucet
- Reduced water pressure
- Frost or ice on exposed pipes
- Strange noises when turning on a faucet
- Unusual odors coming from drains or faucets
- Damp spots or unexplained water around plumbing fixtures
If you suspect a pipe has frozen, avoid using an open flame or other unsafe method to thaw it. A professional plumber can determine where the blockage is located and safely address the issue.
How to Protect Your Plumbing During a Wisconsin Winter
A few preventative steps can reduce the risk of winter plumbing problems:
Insulate exposed pipes. Pipe insulation can help protect plumbing located in cold or poorly insulated areas.
Disconnect outdoor hoses. Remove hoses from exterior faucets before freezing temperatures arrive.
Keep garage doors closed. If plumbing runs through your garage, keeping the space closed can help prevent pipes from being exposed to extreme cold.
Open cabinet doors. During particularly cold weather, opening cabinets beneath sinks can allow warmer household air to circulate around plumbing.
Maintain consistent indoor temperatures. Avoid turning the heat down too far when leaving your home during the winter.
Know where your main water shutoff is located. If a pipe does burst, shutting off the water quickly can help minimize damage.
When to Call a Plumber
Even with preventative measures, Wisconsin’s winter temperatures can put your plumbing to the test. If you notice a frozen pipe, burst pipe, significant drop in water pressure, unexplained leak, or other plumbing issue, professional service can help prevent further damage.
Taking care of potential problems early is often much easier and less expensive than dealing with extensive water damage after a pipe bursts.
Keep Your Plumbing Ready for Wisconsin Winter
Freezing temperatures are simply part of living in Wisconsin, but serious plumbing damage does not have to be. Proper insulation, winter preparation, and regular plumbing maintenance can go a long way toward protecting your home’s plumbing system.
If you are concerned about your pipes or need help preparing your plumbing for another Wisconsin winter, a professional plumbing contractor can inspect vulnerable areas and recommend the right solutions for your home.
