The top causes of burst pipes include freezing temperatures, high water pressure, corrosion, clogs, and improper connections. Tacoma, WA, homeowners can protect their plumbing by insulating exposed pipes before winter, maintaining consistent indoor temperatures, installing a water pressure regulator, scheduling regular drain cleaning, and hiring licensed plumbers for all installations and repairs.

Your plumbing system is one of the most critical and most overlooked systems in your home. A burst pipe can happen without warning, causing extensive water damage, expensive repairs, and major disruptions to your daily routine.

For Tacoma, WA, homeowners, the risk is real year-round. From the cold winter months in Pierce County to the pressure-aging pipes face in older neighborhoods throughout the South Sound, understanding what causes burst pipes is the first step to preventing them.

Here are the most common culprits and what Tacoma homeowners can do to stay ahead of them.

Frozen Water in the Pipes

When temperatures drop, and water inside your pipes freezes, it expands, creating intense pressure that can cause even a well-maintained pipe to burst. This is one of the most sudden and damaging plumbing emergencies a homeowner can face.

In Tacoma and across Pierce County, winter temperatures regularly dip below freezing, especially from December through February. Homes with pipes running through unheated crawl spaces, garages, or along exterior walls are particularly vulnerable. If your home is older or lacks adequate pipe insulation, the risk increases significantly.

What to do: Keep your home heated to at least 55°F even when you’re away. Open cabinet doors under sinks along exterior walls to let warm air circulate. Let a slow drip of water run through faucets during freeze warnings to alleviate pressure buildup inside the pipes. If you’re not sure whether your pipes are adequately insulated, schedule a preventive inspection with a Tacoma plumber before winter hits.

Aged Pipework

As time passes, pipes grow weaker and more prone to failure. Corrosion, rust, and the gradual breakdown of pipe material all reduce a pipe’s ability to hold up under normal water pressure, eventually leading to leaks or full bursts.

Tacoma has a rich housing history, and many homes throughout the city and surrounding areas like Lakewood, Fircrest, and University Place were built decades ago with galvanized steel or cast iron pipes that are now well past their expected lifespan. If your home is more than 30–40 years old and has never had a pipe inspection, it may be running on infrastructure that’s silently deteriorating.

A professional plumber can assess the condition of your pipes and determine whether sections need to be replaced before they fail. Proactive repiping is far less costly than emergency repairs after a burst and far less damaging to your home.

Pressure from Internal and External Forces

High water pressure feels great in the shower, but it puts serious strain on your pipes, joints, and fixtures over time. Sustained excessive pressure can cause pipes to crack, weaken, or eventually burst.

In Tacoma and the surrounding Pierce County communities, water pressure can fluctuate depending on your location, the age of your water main, and changes in municipal supply. If your home’s water pressure is regularly above 80 psi, your pipes are under more stress than they should be. Installing a pressure regulator is a straightforward fix that can extend the life of your entire plumbing system.

External forces matter too. Construction work, nearby excavation, or even heavy landscaping projects near buried pipes can introduce physical stress that leads to burst pipes, often without any visible warning signs until significant damage has already occurred.

Clogs

A clog doesn’t just slow your drain; it creates a pressure buildup inside the pipe that can stress and eventually rupture the pipe walls. Over time, accumulations of grease, debris, mineral scale, and foreign objects can cause serious structural damage.

Tacoma’s older water systems, particularly in neighborhoods with hard water or aging sewer connections, are prone to mineral buildup and root intrusion that compounds clogging issues. Regular professional drain cleaning is one of the most effective and most overlooked ways to prevent burst pipes.

Be mindful of what goes down your drains: avoid grease, paper towels, wipes, and excessive food waste. For deeper pipe health, a sewer camera inspection can reveal developing blockages before they become a crisis.

Improper Connections

When pipes are incorrectly installed or connected with substandard materials, weak joints and loose fittings create failure points throughout your plumbing system. These issues may start as minor drips but can escalate quickly, especially under the pressure of daily use, until a full pipe burst occurs.

This is a common problem in Tacoma homes that have undergone DIY plumbing work or renovations by unlicensed contractors. Even small errors in pipe fitting, joint sealing, or connection type can have serious long-term consequences for your home’s plumbing integrity.
