As the temperature drops, it’s time to think about your home’s plumbing system and how it will weather the winter months. The weather can change to become chilly, damp and frosty, so taking steps to safeguard your plumbing is essential to prevent costly and inconvenient waterworks and heating issues.
In this blog post, we will explore some common concerns for your plumbing and drainage systems in winter, and offer valuable tips to help you care for your pipes and prepare for the cold season.
Prevent Frozen Pipes
One of the most effective ways to protect your winter plumbing is to insulate your pipes. Insulation helps to prevent freezing, which can lead to burst pipes. Common areas that require insulation include:
Exterior pipes
Pipes in unheated areas like the garage or attic
Pipes near exterior walls
Any exposed plumbing
Crawl spaces are also key unheated areas where pipes are vulnerable to freezing and should be insulated.
You can use foam pipe insulation, pipe sleeves, or even newspaper and duct tape to wrap your pipes – foam insulation is an effective and easy-to-install material for protecting pipes from freezing temperatures. It’s a relatively inexpensive way to keep your plumbing cosy. Pipes inside the house, especially those near exterior walls and in crawl spaces, should be properly insulated. Pipes in unheated areas like attics, garages, and crawl spaces, as well as cold pipes and drain pipes, are most at risk during extended periods of low temperatures, and should be properly insulated.
If your pipes do freeze during the winter, it’s essential to act quickly to prevent them from bursting and causing water damage. Here’s what you should do if you discover frozen pipes:
Locate the Frozen Pipes:
Identify which pipes are frozen. Signs of frozen pipes include a lack of water flowing from taps and frost on exposed pipes.
Turn Off the Water Supply:
Shut off the main water supply to your home (stop tap) to prevent additional water from entering the frozen pipes. Make sure you know where your stop tap is and that it is functioning for emergencies. If your home has individual shut-off valves for different sections, you can use those to isolate the affected area. If you have a well pump, turn it off to prevent it from running dry and burning out.
Open the Affected Taps
Open the taps connected to the frozen pipes to relieve pressure. This will also allow the water to escape once the pipes thaw.
Thaw the Pipes:
Use warm towels, hot water bottles or a hairdryer on a warm setting. Do NOT use open flames or high-temperature devices like propane torches to thaw pipes, as this can be dangerous and cause fires or damage the pipes. It is not a good idea to pour boiling water on frozen pipes, as this can cause thermal shock, cracks, or leaks, especially in materials like cast iron or PVC. Pouring boiling water down frozen pipes can also cause small leaks or stress fractures at the joints, and boiling water can soften PVC pipes, leading to sagging and hairline cracks. Instead, using warm water and dish soap is a safer alternative for unclogging or thawing pipes, and warm water can help gently thaw frozen pipes.
Continue Thawing:
Keep applying heat until water flows freely from the taps. This may take some time, so be patient. Start with the tap closest to the frozen area.
Extra Tips:
Keep cabinet doors open to allow warm air to circulate around pipes under sinks, especially in the bathroom sink area. Sealing leaks around windows and doors can help prevent cold air from entering and helps maintain a warm environment for pipes. Dripping faucets during extreme cold can help keep water moving and prevent freezing.
Insulate and Prevent Future Freezing:
Once the pipes are thawed, insulate them to prevent future freezing. Regular checks and maintenance, including plumbing inspections before winter, can help identify potential leaks and issues before they become emergencies.
Check for Leaks:
After the pipes have thawed, check for any leaks. If you notice any damage, you may need to call a plumber to repair or replace the affected section of the pipe. Regular checks and maintenance can make all the difference in preventing a minor plumbing problem from turning into a catastrophe. If basic troubleshooting does not resolve the issue, it may be time to consult a professional.
Don’t forget your Outdoor Plumbing!
This includes garden hoses and outdoor taps. Disconnect and drain hoses, and shut off the outdoor water supply if possible. Draining outdoor faucets and disconnecting hoses is essential for winterizing plumbing systems. After disconnecting, make sure to drain and insulate outdoor pipes to prevent freezing temperatures from causing frozen or burst pipes, which can lead to costly repairs. Seal any gaps and use insulating covers on outdoor faucets to protect against freezing temperatures.
Outdoor drains can freeze in winter, leading to blockages and potential flooding. To prevent this, keep outdoor drains clear of debris and check them regularly to avoid ice buildup and clogs. Regular checks and maintenance of outdoor plumbing can help identify potential issues before they become emergencies.
Service Your Boiler
Your boiler is essential for keeping your home warm and your water hot. Heating systems, including central heating and water heaters, should be checked and maintained before winter to prevent unexpected issues. Boilers and heating systems should be serviced annually by a qualified professional to ensure optimal performance and safety during the colder months. Increased demand for hot water in winter can stress water heaters, leading to malfunctions caused by failing components such as thermostats and heating coils. Some repairs, like replacing heating coils or thermostats, may require professional repair to restore proper function. Timely repairs are crucial to prevent breakdowns and ensure your heating system works efficiently throughout the winter. A well-maintained boiler will be more energy-efficient and less likely to fail during the colder months.
Keep Your Home Warm and plan for Winter Vacations
Maintaining a warm indoor temperature during the winter is not only good for your comfort, but also ideal for protecting your plumbing. Ensure that your heating system is in good working order and set it to a temperature that prevents freezing, typically around 12-15°C (55-60°F). If you’re planning a winter getaway, or leaving the house to stay with family over the Christmas period, it may also be wise to set your heating to come on by timer or get a neighbour to pop in to check your home while you’re away.
Common winter plumbing problems include frozen and burst pipes, clogged drains, water heater strain, and sump pump issues. Clogged drains can occur more frequently in winter due to increased cooking activity and the solidification of fats and oils in pipes. To prevent clogged drains, avoid pouring grease down the drain, as grease can solidify in cold pipes and cause blockages. Sump pump issues may arise from freezing discharge lines or overloaded pumps due to melting snow and ice, which can also affect water pressure and lead to plumbing emergencies. Unusual noises from your plumbing system may indicate a problem and should be checked by a professional plumber.
During extended periods of cold weather, the risk of plumbing problems increases, making regular checks and maintenance essential to prevent minor issues from becoming major plumbing emergencies. Emergency plumbing services are often in high demand during winter, and plumbing companies and plumbers offer a range of services, including emergency repairs and preventative maintenance, to help you avoid costly damage. If you notice any signs of a plumbing emergency, such as leaks, burst pipes, or clogged drains, contact a professional immediately.
