Cold Weather Plumbing Tips to Prevent Frozen Pipes and Costly Leaks

Cold weather in North Mississippi can be unpredictable, and when temperatures drop, your plumbing system can be at risk. One of the biggest winter concerns homeowners face is frozen pipes, which can lead to burst lines, water damage, and unexpected repairs.

At Olive Branch Plumbing Co., we help families protect their homes during cold snaps with simple, practical prevention steps. A little planning now can help you avoid plumbing emergencies later.

Why Cold Weather Can Cause Plumbing Problems

When temperatures fall below freezing, the water inside exposed pipes can freeze and expand. That pressure can cause pipes to crack or burst—often in places you don’t notice until the water starts leaking.

The most common cold-weather plumbing issues we respond to include:

• Frozen outdoor faucets and hose bibs
• Burst pipes in crawl spaces, attics, and exterior walls
• Sudden loss of water pressure or no water at all
• Water heater strain from extra demand
• Hidden leaks that show up after a thaw

These problems tend to happen fast, and they almost always happen at the worst time.

Protect Exposed Pipes Before the Next Cold Snap

Some pipes are more vulnerable than others—especially those near outside walls or in unheated areas.

To help prevent freezing:

• Insulate exposed pipes in crawl spaces, garages, and attics
• Seal air leaks around plumbing penetrations in walls
• Open cabinet doors under sinks to allow warm air to circulate
• Keep your thermostat set consistently, even overnight

If your home has a history of frozen pipes, it may be worth adding pipe insulation or heat tape in key areas.

Don’t Forget Outdoor Faucets and Hose Connections

Outdoor plumbing is one of the first things to freeze.

A few quick steps can reduce your risk:

• Disconnect all hoses from outdoor spigots
• Shut off and drain outdoor water lines if your home has a dedicated valve
• Cover exterior faucets with insulated faucet covers
• Check sprinkler or irrigation components for winter vulnerability

Even a small freeze can damage an outdoor faucet and cause leaking inside the wall once temperatures rise.

What to Do If You Suspect a Frozen Pipe

If water flow slows down or stops during freezing temperatures, you may have a frozen line.

Here’s what you should do right away:

• Turn off the water supply if you see any signs of pipe damage
• Keep the faucet open slightly to relieve pressure
• Use a hair dryer or warm towels to gently thaw the pipe
• Avoid open flames or high-heat tools that can damage pipes

If a pipe has burst, shut off your main water valve and call a professional immediately.

Winter Water Heater Struggles You Shouldn’t Ignore

When temperatures drop, water heaters often work harder to maintain steady hot water—especially with families home more and using extra hot water.

Signs your water heater may need attention:

• Hot water runs out faster than normal
• Water takes longer to heat up
• Strange noises coming from the tank
• Rust-colored water or inconsistent temperature

A quick inspection and flush can help extend the life of your system and improve performance.

A Little Winter Plumbing Prep Can Save You a Big Headache

Before freezing temperatures hit, a quick check can make a big difference:

• Inspect visible pipes for cracks or corrosion
• Test shut-off valves to make sure they work
• Look under sinks for slow leaks
• Check your water heater for unusual sounds or changes
• Make sure your home’s main shut-off valve is easy to access

Small issues during cold weather can become major problems quickly, so catching them early is always the better option.
