Winter brings its share of cozy evenings and snowy landscapes, but it also introduces unique challenges for your home’s plumbing system. Frozen pipes and clogged drains are common issues that can lead to costly repairs if not addressed. With a little preparation, you can protect your plumbing and keep your home running smoothly throughout the colder months.
Why Do Pipes Freeze in Winter?
When temperatures drop, the water inside pipes can freeze, expanding and creating pressure. This pressure can cause pipes to crack or burst, leading to significant water damage. Similarly, cold temperatures can cause grease, soap scum and debris to harden in drains, increasing the risk of clogs.
Top 5 Tips for Winterizing Your Plumbing
1. Insulate Your Pipes
Wrap exposed pipes with foam insulation or heat tape to prevent freezing. Focus on pipes in unheated areas like basements, garages, and crawl spaces.
2. Seal Gaps and Cracks
Inspect your home for drafts or gaps near pipes, especially where they enter walls. Use caulk or spray foam to seal these openings and prevent cold air from reaching the pipes.
3. Keep Faucets Dripping
Allowing a slow drip of water from faucets during freezing weather can relieve pressure in the pipes and reduce the risk of bursting.
4. Disconnect and Drain Outdoor Hoses
Remove and store garden hoses, then drain the outdoor faucet. Consider installing a frost-proof faucet cover for extra protection.
5. Maintain a Consistent Indoor Temperature
Set your thermostat to at least 13°C(55°F) even when you’re away. Keeping the temperature consistent reduces the risk of pipes freezing.
Preventing Clogged Drains in Winter
Cold temperatures can also worsen clogs in your drains. Here’s how to avoid them:
Dispose of Grease Properly: Never pour grease or oil down the drain; instead, let it solidify and dispose of it in the trash.
Use Drain Strainers: Place strainers over drains to catch food debris and hair.
Run Hot Water Regularly: Flushing hot water through your drains helps dissolve soap scum and keeps pipes clear.
Avoid Overloading Your Garbage Disposal: Break food scraps into smaller pieces, and run cold water while using the disposal to help it function properly.
Emergency Steps for Frozen Pipes

If you suspect a frozen pipe, act quickly to prevent it from bursting:
- Turn Off the Main Water Supply: This minimizes water damage if the pipe bursts.
- Apply Heat: Use a hairdryer, heating pad, or warm towels to gently thaw the pipe. Never use an open flame.
- Open Faucets: Allow water to flow once the pipe begins to thaw, helping melt the ice.
- Call a Professional: If you’re unable to locate or thaw the frozen pipe, contact a plumber immediately.
