What Causes Pipes to Burst, And How Can You Prevent It?

A burst pipe isn’t just a plumbing issue—it’s an emergency that can lead to thousands of dollars in property damage, major disruptions, and costly repairs.

Unfortunately, pipe bursts are more common than many people realize, especially in areas like Houston, where sudden temperature swings, soil movement, and aging infrastructure all play a role.

In this blog, we’ll walk through what causes pipes to burst, the specific risks for Houston homeowners and businesses, and what steps you can take to protect your property. We’ll also explain how regular inspections and maintenance can dramatically reduce your risk.

What Happens When a Pipe Bursts?

When a pipe bursts, water flows uncontrolled through a split or crack in the line. This can happen anywhere—behind walls, under floors, or even underground. The damage often begins immediately and can quickly flood parts of your home or building.

Burst pipes can lead to:

  • Water damage to floors, drywall, ceilings, and electrical systems
  • Mold growth within 24–48 hours
  • Structural weakening of your property
  • Higher water bills due to wasted water
  • Interrupted water supply

Because of how rapidly things can escalate, a burst pipe almost always requires immediate help from an emergency plumber.

Common Causes of Burst Pipes

Many different issues can cause a pipe to burst. Some develop slowly over time, while others happen suddenly. Below are the most common causes:

1. Freezing Temperatures

When water freezes, it expands inside the pipe. If there’s no room for expansion, internal pressure builds until the pipe cracks or ruptures. This is more common in pipes located in:

  • Uninsulated exterior walls
  • Attics or basements
  • Crawl spaces
  • Outdoor spigots or irrigation lines

Even in warmer areas like Houston, winter freezes can come unexpectedly, making this a year-round concern.

2. Corrosion

Pipes degrade with age. Galvanized steel, copper, and even some types of PVC can corrode over time. Corrosion weakens the pipe wall and makes it prone to failure under normal water pressure.

If your home was built more than 30 years ago and hasn’t had a plumbing update, your risk is significantly higher.

3. High Water Pressure

Plumbing systems are designed to handle water pressure between 40 and 80 psi. Pressure above that threshold puts added stress on fittings, joints, and pipe walls. Eventually, the pressure can cause a rupture—especially if there’s a weak spot.

Signs of high pressure include:

  • Banging noises when turning off faucets
  • Leaky fixtures
  • Sudden bursts of water from taps

4. Clogs and Blockages

When a drain or sewer line becomes clogged, pressure builds up behind the blockage. This uneven pressure can eventually cause the pipe to crack or burst—especially near bends or fittings.

Clogs often result from:

  • Grease buildup
  • Tree root intrusion
  • Hair, debris, or foreign objects
  • Scale buildup from hard water

5. Poor Installation or Low-Quality Materials

Improper installation—such as unsupported joints, poor connections, or substandard materials—can lead to early pipe failure. DIY plumbing projects or unlicensed work are often the root of these issues.

Over time, minor leaks or pipe shifts can grow into a full rupture.

6. Soil Movement or Foundation Shifts

Houston’s clay-heavy soil expands when wet and contracts when dry. This constant shifting puts pressure on underground pipes and slab foundations. If a pipe is already aging or poorly supported, even small shifts can lead to a break.

7. Tree Root Intrusion

Roots are naturally drawn to moisture. Small cracks in underground pipes can attract roots, which then grow inside the pipe and widen the opening. Over time, this pressure causes the pipe to burst or collapse completely.

Why Pipe Bursts Are Common in Houston

Houston presents a unique mix of risk factors for pipe failure:

Weather Extremes: While winters are usually mild, occasional freezes catch homeowners off guard. Many Houston homes lack adequate pipe insulation.

Clay Soil: Expansive clay soil in the region causes significant ground movement, which shifts and stresses plumbing lines.

Aging Infrastructure: Many homes and commercial buildings in Houston are decades old and still rely on original plumbing systems.

Rapid Growth: Increased development has placed added stress on older water infrastructure throughout the area.

According to Texas Monthly, aging and leaking pipes are wasting billions of gallons of water every year across Texas. Burst pipes aren’t just a personal problem—they’re part of a much larger infrastructure challenge statewide.

How to Prevent Pipes from Bursting

While some pipe failures happen unexpectedly, many are preventable. Here are steps you can take to protect your plumbing system:

1. Insulate Vulnerable Pipes

  • Use pipe insulation or foam sleeves on exposed pipes in unheated areas
  • Pay special attention to pipes in basements, attics, crawl spaces, and garages

2. Keep Pipes Warm During Cold Snaps

  • Open cabinet doors to allow warm air to circulate around under-sink pipes
  • Let faucets drip slowly to relieve pressure
  • Use heat tape or heating cables for high-risk pipes

3. Monitor Water Pressure

  • Install a water pressure gauge or have your plumber test it
  • Use a pressure-reducing valve if pressure consistently exceeds 80 psi

4. Fix Small Leaks Promptly

  • Even a slow drip can indicate a weak joint or corrosion
  • Early repairs reduce the risk of future pipe failure

5. Trim Trees Near Water Lines

  • Keep root systems away from underground pipes
  • Consider barrier systems for problem trees

6. Install Leak Detectors

  • Smart water sensors can alert you to leaks or unexpected water flow
  • Early detection helps prevent large-scale damage

7. Schedule Annual Plumbing Inspections

  • Professionals can identify weak points, corrosion, or early signs of blockages
  • Inspections are especially important for older properties

The Importance of Plumbing Maintenance

One of the most effective ways to prevent burst pipes is by scheduling regular plumbing maintenance. TX Hydrojet offers plumbing maintenance services for homeowners, businesses, and property managers across the Houston area.

Our maintenance plans include:

  • Full system checks
  • Drain cleaning
  • Video pipe inspections
  • Leak detection
  • Water pressure evaluations

By addressing small problems before they escalate, you avoid emergencies, lower your long-term costs, and extend the life of your plumbing system.

If you’re concerned about pipe safety or have an older system, now is the time to take action. Preventative care saves time, money, and stress down the line.

What To Do If a Pipe Bursts

Despite your best efforts, pipe failures can still happen. If one bursts, act fast:

  1. Shut Off the Water: Locate your main shut-off valve and turn it off immediately
  1. Turn Off Electricity: If water is near electrical outlets, switch off the power to the affected area
  1. Move Valuables: Clear the area to prevent further damage
  1. Call an Emergency Plumber: TX Hydrojet provides fast, 24/7 emergency service. We arrive within 60 minutes and act quickly to stop the damage

Your Burst Pipe Questions

What causes pipes to burst in cold weather?

When water freezes, it expands. This creates pressure inside the pipe that can cause it to split or rupture.

Can burst pipes be repaired, or do they need replacement?

It depends on the extent of the damage. Some pipes can be patched or partially replaced; others may need full replacement.

Is it safe to use pipe insulation year-round?

Yes. Insulation protects pipes in cold weather and also helps regulate temperature in summer.

What does a burst pipe sound like?

You may hear a loud pop or whooshing sound, followed by water dripping or a gushing sound behind walls or in ceilings.

How can I test my water pressure?

You can use a simple pressure gauge at a hose bib or ask a licensed plumber to evaluate it.

Are all pipe materials equally at risk?

No. Older galvanized steel pipes are more prone to corrosion. Modern PEX and copper pipes last longer but can still burst under certain conditions.

What are the signs of a hidden pipe leak?

Unexplained water stains, mold growth, musty odors, or high water bills could indicate a hidden leak.

Will homeowners insurance cover burst pipe damage?

Most policies cover sudden burst pipe damage but not issues caused by neglect or poor maintenance.

How often should I schedule plumbing maintenance?

At least once a year—or more frequently for older homes or commercial buildings.

Can burst pipes happen in summer?

Yes. High pressure, tree roots, and corrosion can cause pipe bursts even in warm weather.
