Anyone who has lived through a Chicago winter knows that cold weather here is not just uncomfortable—it can also be hard on your home, especially when it comes to plumbing. While a heavy coat and a good shovel may be enough to get you through the season personally, your pipes need a little more attention when temperatures drop and stay there.
Frozen pipes are one of the most common winter plumbing issues homeowners face, and they often occur with little warning during extreme cold snaps. Understanding how and why pipes freeze can help you take simple, proactive steps to reduce the risk before real damage occurs.
Why Frozen Pipes Are More Than Just an Inconvenience
When water freezes inside a pipe, it expands, creating pressure that can cause the pipe to crack or burst. This pressure buildup is especially dangerous because the damage often isn't visible until the ice thaws and water begins leaking into walls, ceilings, or floors.
Even a small break in a pipe can release a surprising amount of water in a short period of time, leading to costly repairs, structural damage, and mold growth. Preventing frozen pipes is far easier—and far less stressful—than dealing with the aftermath of a burst pipe in the middle of winter.
Should I Let My Faucets Drip When Temperatures Drop?
Homeowners often ask, should I let my faucets drip? The answer depends on the weather conditions, but during prolonged periods of freezing temperatures, allowing a small, steady drip can be an effective preventive measure.
Letting water flow, even slowly, helps relieve pressure inside the pipes and makes it less likely that ice will fully block the line. This is why many plumbers recommend dripping faucets during freeze events, particularly in homes with older plumbing or pipes located along exterior walls.
How Dripping Faucets During Freeze Conditions Protect Pipes
Dripping faucets during freeze conditions work because moving water is less likely to freeze than water sitting still inside a pipe. Even a slight flow helps prevent pressure from building up behind ice formations, which is often what causes pipes to burst.
You don't need to leave water running at full strength. A slow, consistent drip is usually enough, especially when combined with other precautions such as keeping cabinet doors open or maintaining a steady indoor temperature. This method is simple, affordable, and surprisingly effective during extreme cold.
When to Let Faucets Drip in Cold Weather
You don't need to let faucets drip all winter long, but it's smart to do so when temperatures are expected to remain below freezing for several hours or overnight. It's especially important to let faucets drip in cold weather if your home has pipes in unheated spaces like basements, crawl spaces, garages, or along exterior walls.
Homes with inconsistent heating or limited insulation are also more vulnerable, making this small step an important layer of protection during severe cold spells.
How to Let Water Drip to Prevent Freezing More Effectively
If you decide to let water drip to prevent freezing, there are a few additional steps that can improve the results. Opening cabinet doors under sinks allows warm air to circulate around exposed pipes, while keeping interior doors open helps heat move more evenly throughout the home.
Maintaining a consistent thermostat setting, even overnight, and sealing drafts near windows or foundation walls can further reduce the chances of frozen pipes during extreme winter weather.
Reducing Water Waste While Faucets Are Dripping
It's normal to worry about water usage when dripping faucets during freeze periods, but the amount of water used is minimal compared to the damage a burst pipe can cause. If you want to be more mindful, you can place a container under the drip and reuse that water for cleaning or household tasks.
This approach allows you to protect your plumbing without feeling wasteful during cold weather.
A Few Extra Steps to Prevent Frozen Pipes
While dripping faucets is helpful, it works best as part of a broader winter preparation plan. Insulating exposed pipes, disconnecting outdoor hoses, draining exterior spigots, and sealing air leaks around your home all contribute to keeping pipes from freezing.
Taking these precautions early can save you from emergency repairs when temperatures drop suddenly.
Stay Prepared All Winter Long
Chicago winters are unpredictable, but frozen pipes don't have to be. Knowing when to let faucets drip in cold weather and how to support that effort with other preventive steps can go a long way toward protecting your home and avoiding unnecessary damage during extreme temperatures.
