Common Causes of Burst Pipes & How to Prevent Them

A homeowner's Guide to Burst Pipes

One of the most common reasons pipes burst is freezing weather. When water inside a pipe freezes, it expands. This expansion creates intense pressure inside the pipe, which can cause it to crack or burst.

How to Prevent It

• Insulate pipes in cold areas such as basements, attics, and garages
• Let faucets drip slightly during extreme cold
• Keep your home heated even if you’re away
• Open cabinet doors under sinks to allow warm air to circulate



If a pipe freezes or bursts, contacting an emergency plumber promptly can help minimize water damage.

While strong water pressure might feel great in the shower, excessive pressure can strain your plumbing system. Pipes are designed to handle a certain level of pressure. When the pressure exceeds safe limits, pipes and joints can weaken and eventually burst.

How to Prevent It

• Install a water pressure regulator
• Test your water pressure periodically
• Keep pressure below about 60 PSI



If you suspect dangerously high water pressure, an emergency plumber can inspect your system and recommend the proper solution.

Over time, pipes can corrode, weaken, and deteriorate. Older plumbing systems—especially those with galvanized steel pipes—are particularly vulnerable. Corroded pipes become thin and fragile, making them more likely to burst unexpectedly.

How to Prevent It

• Schedule routine plumbing inspections
• Replace aging pipes before they fail
• Watch for signs like discolored water or a metallic taste



If corrosion leads to a sudden pipe failure, calling an emergency plumber immediately can prevent extensive structural damage.

Severe clogs can create pressure buildup within pipes. When water cannot flow properly through the plumbing system, it can cause pipes to expand and eventually burst. Some common causes of clogs include grease buildup, hair and soap residue, and foreign objects flushed down drains. 

How to Prevent It

• Avoid pouring grease down drains
• Use drain screens in sinks and showers
• Schedule regular drain cleaning

If a clog causes a pipe to rupture, an emergency plumber can quickly clear the blockage and repair the damaged pipe.

Tree roots naturally seek out water sources. Over time, roots can grow toward underground pipes and penetrate small cracks or joints. Once roots enter the system, they can block water flow, expand inside pipes, or cause pipes to split or burst.



How to Prevent It

• Avoid planting large trees near sewer lines
• Schedule routine sewer line inspections
• Address slow drains early

A professional emergency plumber has specialized tools to remove root intrusions and repair damaged pipes.

Recognizing early warning signs can help prevent a full plumbing emergency. Watch for:

• Unusual banging or clanking sounds in pipes
• Reduced water pressure
• Water stains on walls or ceilings
• Unexplained increases in water bills
• Damp or musty odors



If you notice any of these signs, it’s best to contact an emergency plumber before the situation worsens.

If a pipe bursts in your home, acting quickly is essential.

1. Shut off the main water supply
2. Turn off electricity near flooded areas if safe
3. Drain remaining water by opening faucets
4. Remove excess water and protect belongings
5. Call an emergency plumber immediately for professional repairs



Fast action can significantly reduce damage and repair costs.

Burst pipes can cause significant disruption and costly repairs, but many plumbing emergencies can be prevented with proper maintenance and awareness. By protecting pipes from freezing, monitoring water pressure, addressing corrosion, and preventing clogs, homeowners can greatly reduce the risk of pipe failures.
