5 Common Causes of Burst Pipes

Top 5 Common Causes of Burst Pipes in Residential Homes

Water damage is one of the most expensive headaches a homeowner can face. When a pipe fails, it often happens without any warning and dumps hundreds of litres of water into your rooms in minutes. While it might seem like a random stroke of bad luck, plumbing systems usually fail due to specific physical pressures.

At Sharpe Trade Services, we have been providing emergency plumbing in Adelaide since 1980. Understanding the mechanics behind these failures helps you maintain your home and avoid costly emergency repairs.

1. Freezing Temperatures and Ice Expansion

In many parts of Australia, particularly in the southern states or the Adelaide Hills, overnight temperatures drop below zero. Physics dictates that water expands when it turns into ice. When water freezes inside a copper or plastic pipe, it puts immense internal pressure on the pipe walls, eventually exceeding the strength of the material and causing a burst.

2. High Water Pressure

While a high-pressure shower feels great, excessive force ruins your plumbing. Most residential pipes handle pressure between 350 and 500 kPa. If your pressure exceeds 500 kPa, it puts constant stress on joints and valves. This often leads to a “water hammer”—that banging sound you hear in your walls—which weakens the system over time.

3. Corrosion and Ageing Materials

Plumbing systems do not last forever. Older Adelaide homes often contain galvanised steel or older copper. Over decades, these react with minerals in the water, leading to corrosion that thins the pipe walls from the inside out. If your water looks brown or tastes metallic, your structural plumbing integrity may be failing.

4. Invasive Tree Roots

Trees are experts at finding moisture. Even a hairline crack in an underground pipe releases water that attracts roots. Once a root enters a joint, it expands like a slow wedge, forcing the pipe apart. This is a frequent cause of blocked drains and burst supply lines in leafy suburbs.

5. Movement and Shifting Soil

Adelaide is known for its reactive clay soils. These soils swell during the winter rains and shrink during the summer heat. This constant movement puts physical stress on rigid pipes like PVC or copper. If the soil shifts enough, the pipe will bend until it snaps—a common issue in both older areas and new developments.
