Common Winter Plumbing Myths That Can Actually Damage Your Pipes

When winter hits Anne Arundel County, homeowners start sharing advice—neighbors, family members, social media posts—all claiming to have the “simple trick” that prevents frozen pipes. Unfortunately, some of the most common winter plumbing tips are myths that can actually cause serious damage.

Knowing what not to do is just as important as knowing what to do when temperatures drop. Let’s clear up a few winter plumbing myths that could put your home at risk.

Myth #1: Letting Faucets Drip Solves Everything

You’ve probably heard this one before: just let your faucets drip and you’ll never have frozen pipes. While dripping a faucet can help reduce pressure in the system, it does not guarantee protection—especially in older Anne Arundel County homes or during extended cold snaps.

Dripping water only helps if the pipe is already well insulated and the cold exposure is minimal. If pipes are located in exterior walls, crawl spaces, or unheated areas, dripping alone won’t prevent freezing. In some cases, homeowners assume dripping means they’re safe and skip more important steps like insulating pipes or opening cabinet doors to allow warm air to circulate.

What actually helps: proper insulation, sealing air leaks, maintaining indoor temperatures, and knowing where your shutoff valve is located.

Myth #2: Pouring Boiling Water Will Clear Frozen Pipes

This is one of the most dangerous winter plumbing myths. Pouring boiling water down a frozen drain or onto exposed pipes can cause sudden temperature changes that crack or burst pipes—especially PVC or older metal piping.

Frozen pipes need to thaw slowly and evenly. Rapid heating increases pressure inside the pipe, which is often what causes it to burst. Many emergency plumbing calls in winter start with “we tried to fix it ourselves.”

What actually helps: gentle warming methods, such as warm air from a hair dryer, heating pads designed for pipes, or professional assistance if the pipe isn’t accessible.

Myth #3: Pipes Only Freeze When It’s Below Zero

Many homeowners assume frozen pipes only happen during extreme cold, but that’s not the case in Anne Arundel County. Pipes can freeze when temperatures drop below 32 degrees—especially overnight when water isn’t moving and heat levels dip.

Homes with poor insulation, drafty basements, or pipes near exterior walls are particularly vulnerable. This myth often leads homeowners to let their guard down during “milder” winter weather, only to be caught off guard by a frozen or burst pipe.

Myth #4: If Nothing Has Happened Yet, You’re in the Clear

Just because your pipes made it through the first cold snap doesn’t mean you’re safe for the rest of winter. Repeated freeze-and-thaw cycles weaken pipes over time. Small cracks can form and go unnoticed until pressure builds or temperatures drop again.

Ignoring early warning signs—such as reduced water flow, frost on pipes, or unusual noises—can lead to sudden failures later in the season.

The Safer Way to Protect Your Plumbing This Winter

Avoiding winter plumbing damage isn’t about shortcuts—it’s about understanding how your system actually works. Taking proactive steps, addressing small issues early, and avoiding risky DIY fixes can save you from major repairs and water damage.
