Frozen Pipes: What North Texas Homeowners Need to Know

Freezing temperatures may not happen every week in North Texas, but when a hard freeze hits the Dallas-Fort Worth area, your home’s plumbing can be at risk.

Water expands when it freezes. When water inside a pipe freezes, the resulting ice can create pressure within the plumbing system and contribute to cracked pipes, failed fittings, and water leaks. In some cases, homeowners don’t realize a pipe has been damaged until temperatures rise and the frozen section begins to thaw.

A frozen or burst pipe can quickly release a significant amount of water into walls, ceilings, cabinets, flooring, or other areas of your home.

Knowing how to recognize a frozen pipe, what to do if your pipes freeze, and how to prevent frozen pipes can help protect your home during the next North Texas freeze.

Total Plumbing Service Inc. has served homeowners throughout the Dallas-Fort Worth (DFW) Metroplex since 1996. Here’s what our team recommends homeowners know before temperatures drop.

Why Do Pipes Freeze?

Pipes freeze when the water inside them is exposed to sufficiently cold temperatures for long enough to turn into ice.

Not every pipe in your house faces the same level of risk.

Plumbing is generally more vulnerable when it’s located in areas that receive little heat or protection from outside temperatures.

Common locations include:

• Exterior walls

• Garages

• Attics

• Crawl spaces

• Outdoor kitchens

• Exterior faucets

• Unheated utility areas

• Poorly insulated portions of the home

North Texas homes can be particularly susceptible because many aren’t designed for extended periods of extreme cold.

When unusually low temperatures remain in the area for hours or days, plumbing that normally handles our mild winters can become vulnerable.

How Can You Tell if Your Pipes Are Frozen?

One of the most obvious warning signs is turning on a faucet and getting little or no water.

You may also notice:

• Significantly reduced water pressure

• No water from one particular fixture

• Frost on exposed piping

• Unusual noises from plumbing

• A toilet that won’t refill

• Multiple fixtures losing water simultaneously

If one faucet isn’t working but others throughout the house are operating normally, the frozen section may be isolated to the piping supplying that fixture.

If several areas of the house suddenly have no water, the problem may involve a larger portion of the plumbing system.

What Should You Do if a Pipe Freezes?

If you suspect a frozen pipe, don’t panic—but don’t ignore it either.

First, determine whether you can safely identify the affected area.

If the pipe is accessible, inspect it for visible cracks, bulging, or other signs of damage.

Know where your main water shutoff valve is located and be prepared to turn it off. A frozen pipe may already be damaged even if you can’t see any leaking water.

The ice inside the pipe can temporarily prevent water from escaping.

Once it melts, the damaged section may begin leaking.

Never Use an Open Flame on a Frozen Pipe

Never attempt to thaw a frozen pipe with a propane torch, lighter, candle, or another open flame.

This creates a serious fire hazard and can damage the plumbing itself.

Rapid or excessive heating can also create additional problems.

If an accessible pipe can safely be warmed, gradual warming is preferable. However, homeowners should be cautious when attempting to thaw plumbing themselves because a damaged pipe may begin leaking as soon as the ice melts.

If you’re unsure about the condition or location of the frozen plumbing, call a licensed plumber.

What Happens When Frozen Pipes Thaw?

This is one of the most important things homeowners need to understand.

A frozen pipe doesn’t necessarily leak while it’s frozen.

If the pipe cracked during the freeze, the ice may temporarily block water from escaping.

When temperatures rise and the ice begins melting, water can start flowing through the damaged area.

That’s why homeowners should continue monitoring their plumbing even after the weather warms up.

After a freeze, check for:

• Water inside cabinets

• Damp walls or ceilings

• Wet flooring

• Water around exterior walls

• Unexplained running-water sounds

• Reduced water pressure

• Water meter movement when fixtures are off

If you notice any of these symptoms, shut off your water if necessary and contact a plumber.

What Should You Do if a Pipe Bursts?

If you discover a burst pipe, the first priority is stopping the water.

Shut Off Your Main Water Supply

Turn off your home’s main water shutoff valve as quickly as possible.

Knowing where this valve is located before an emergency happens can save valuable time.

Open a Faucet

After shutting off the main water supply, opening a faucet may help relieve remaining pressure and allow water to drain from the plumbing system.

Protect Your Property

If it’s safe, move furniture, electronics, rugs, and other belongings away from the affected area.

Call a Licensed Plumber

The damaged plumbing needs to be properly located and repaired before the water supply is restored.

If significant water has entered your home, you may also need professional water-remediation services.

How to Prevent Frozen Pipes

Prevention is much easier than dealing with water damage after a pipe bursts.

When freezing weather is forecast for North Texas, take time to prepare your plumbing.

Disconnect Garden Hoses

Remove hoses from exterior faucets before freezing temperatures arrive.

Water trapped inside a connected hose or faucet assembly can freeze and potentially contribute to plumbing damage.

Protect Exposed Pipes

Identify water lines in garages, attics, crawl spaces, exterior walls, and other cold areas.

Appropriate pipe insulation can provide additional protection.

If a particular pipe froze during a previous winter, give that area extra attention.

Keep Your Home Heated

If you’re leaving town during the winter, don’t completely turn off your home’s heat when freezing temperatures are possible.

Interior plumbing relies partly on warmth from your home for protection.

Open Sink Cabinets When Appropriate

During extreme cold, opening cabinet doors beneath sinks located against exterior walls may allow warmer household air to circulate around the plumbing.

If you have children or pets, make sure cleaning supplies and other hazardous products remain safely secured.

Know Where Your Water Shutoff Is

This simple preparation can make an enormous difference.

Find the valve now.

Make sure it’s accessible and that the adults in your household know how to use it.

If a pipe bursts at 2 a.m. during a freeze, you don’t want to spend 20 minutes figuring out how to stop the water.

Should You Drip Faucets During a Freeze?

Allowing a small amount of water to move through vulnerable plumbing may be appropriate in some freezing conditions.

However, dripping a faucet shouldn’t be your only freeze-protection strategy.

Your home’s construction, plumbing layout, insulation, pipe location, and the severity of the freeze all matter.

Protecting exposed plumbing and maintaining appropriate heat inside the home remain important.

Check Your Plumbing After Every Hard Freeze

Even if everything appears normal during the freeze, inspect your plumbing once temperatures rise.

Pay attention to your water meter as well.

Turn off all fixtures and appliances using water and check whether the meter continues indicating usage.

If it does, you could have a leak that isn’t immediately visible.

Professional water leak detection can help determine whether a pipe was damaged during the freeze and locate hidden water leaks.

Can Frozen Pipes Cause a Slab Leak?

Plumbing beneath a concrete slab generally has more protection from outside air temperatures than exposed piping.

However, freeze events can affect different homes in different ways depending on plumbing configuration, depth, insulation, construction, and other factors.

If you notice unexplained water usage, warm or wet flooring, reduced pressure, or other signs of a hidden leak following extreme weather, it’s worth having the plumbing system evaluated rather than assuming the problem is freeze-related.

Accurate diagnosis should come before repair.

Don’t Wait Until the Next North Texas Freeze

One of the best times to prepare for frozen pipes is while the weather is still comfortable.

Walk around your home and identify exterior faucets, exposed pipes, vulnerable plumbing areas, and your main water shutoff.

Address existing leaks and damaged outdoor faucets before temperatures drop.

A few minutes of preparation can potentially prevent a major plumbing emergency later.
