Winters are beautiful, but the cold weather can really be hard on the plumbing system. There are several issues that can be challenging on the pipes and other systems, such as septic tanks, water heaters, etc. During extreme cold, the pipes may freeze, leading to pipe bursts, which may damage the home’s structure. Understanding common winter plumbing problems can help you take necessary measures to prevent costly damage and disruptions.
This blog discusses some common plumbing problems that homeowners usually face in winter so that you are prepared for the winter in advance.
6 Common Winter Plumbing Problems
Here are some problems that winter may bring upon the plumbing system in your home -
Frozen Pipes

If you notice a slow trickle instead of a steady flow, frost on your pipes, or hear strange noises from your plumbing, you might have a frozen pipe issue. When water freezes, it results in the expansion of the pipes, which may cause it to burst. This may result in costly repairs and water damage. So, when winter arrives, it is advisable to check on the pipes as early detection can minimize the damage.
Here’s how to prevent pipes from freezing -
-
Before winter arrives, consider insulating the pipes in the basement, attics, and crawl spaces. Use foam pipe insulation, as they are easy to install and can be cut to adjust to any size.
-
Always set your thermostat to at least 55 degrees Fahrenheit. For the pipes under the sink, open the cabinets to let the warm air circulate through the pipes, which will keep them from freezing. Also, seal the leaks around doors and windows to keep out the cold air.
-
Winterize the plumbing system, drain outdoor faucets, and disconnect hoses. Also, use anti-freezing products to protect the pipes from freezing, prevent evaporation, and maintain the trap seal.
Sump Pump Issues

During winter months, sump pumps often face heavier use because of melting ice and snow. This can lead to backups caused by blockages or freezing. A malfunctioning sump pump can result in a flooded basement, which leads to extensive property damage. Hence, it is advisable to perform regular maintenance to prevent water-related issues and provide reassurance throughout the winter season.
Here are some prevention tips for sump pump issues -
-
It is advisable to maintain the sump pump proactively during fall. Keep the sump pit clear of any debris and grime that could cause clogs.
-
Test them regularly to ensure they are functioning properly. Also, consider keeping the heat on in basements or anywhere the sump pump is located. This prevents the pits and pipes from freezing.
-
Install rerouting gutter drains to redirect the water away from the home’s foundation. Also, ensure that the pump’s intake and discharge lines are free from blockages.
-
Lastly, don’t forget to insulate the discharge lines, as it protects them from freezing.
Clogged Drains

When you flush something down the drain, it gets collected in pipes, be it soap scum, hair, sludgy cooking substance, etc. When winter arrives, anything inside the pipes can solidify, stiffen, or freeze with the water in it. This may leave you with disrupted water flow.
Here’s how to keep the drains from clogging -
-
Avoid putting grease, oil, fat, coffee grounds, bones, etc., that can cause clogs into the garbage disposal. Instead, you can consider disposing of these items in the trash.
-
Use ice cubes in the garbage disposal to help clean and maintain its performance.
-
Run cold water while the disposal is in use, and continue running cold water for at least 15-30 seconds.
Water Heater Problems

A water heater is one of the most used appliances during winter. However, too much use can cause the accumulation of deposits or sediments in your hot water tank and other internal components, which can cause problems. Also, if the pilot light goes out after being relit again, there might be a problem with the gas supply or thermocouple. Sometimes, the water heater may not give out perfect heating or may give out discolored water with a foul odor.
Here’s how to prevent water heater problems during winter -
-
Flush the tank at least once a year to remove sediment buildup, as it may reduce the efficiency of the appliance and cause potential damage to it.
-
Check the anode rod and replace it if required. It prevents corrosion, which can extend the life of your water heater.
-
Insulate the water heater and pipes surrounding it. It protects the pipes and prevents them from freezing. Using an insulating blanket works fine, as it traps the heat in.
Septic System Issues

A poorly insulated septic tank is at greater risk of freezing during winter. If the main pipe connecting the home’s drain to the septic tank freezes, it can cause the system to stop working. When the septic tank becomes full, the waste materials inside may freeze and cause backups. This can lead to sewage leaks, resulting in property damage and possible contamination of the water supply.
Here’s how to prevent your septic tank from freezing -
-
Before winter starts, fill in the area where the tank sits with soil to insulate the system properly. Ensure not to compress the soil. This will cause it to freeze faster.
-
To add an extra layer of insulation, consider adding straw over the tank and its lines.
-
Get the tank pumped, and make sure not to overwhelm the tank. Reduce the garbage disposal and flush it regularly.
-
Also, don’t drive over the drain field, as it compacts the soil, leaving it vulnerable to freezing. Moreover, aerate the soil above the septic field during fall to avoid soil compaction.
Frozen Water Inside Well Pump

Well, pumps are an affordable and convenient source of water for many. However, private wells may face issues during winter due to freezing conditions. Deep wells, though, do not freeze, but jet pumps are more vulnerable, as they must retain water constantly.
To ensure the well pump is working fine, you must know how to winterize your well pump -
-
Select a well-insulated area that is not directly exposed to cold for the jet well pump.
-
Insulate the pump lines to ensure the water inside does not freeze.
-
If the jet well pump freezes, it is advisable to replace the entire unit. This is because if the water expands, it’ll crack the device’s body made up of cast iron.
-
If you find the pumps freezing, turn them off to allow them to thaw.
Conclusion
Cold weather can severely affect your plumbing, as it may clog the drain, freeze pipes and drains, cause trouble to your water heater, freeze the septic tank, etc. There are several methods you can incorporate to protect the plumbing system from freezing. However, if the pipes are frozen, it is advisable not to try to thaw them by yourself, as it may lead to further damage to the plumbing system. Instead, call a professional, as they can help you thaw and defrost your pipes and plumbing system.
