Many people choose Brisbane due to its moderate climate, however, the truth is, the weather here can get quite hot , humid, rainy, and experience seasonal swings like anywhere else. It’s also commonly believed that only freezing temperatures can damage pipes, but this isn’t entirely true either. High temperatures, humidity, heavy rainfall, and climate fluctuations can also place stress on pipe work.
This article will address these common misconceptions, explore how Brisbane’s climate can be tougher on pipes than many may think, and how early pipe leak detection can help minimise issues.
Why Brisbane’s Climate Is Harder on Pipes Than Many Think
While Brisbane’s climate may seem moderate, it can still place stress on pipework. Pipes can experience thermal expansion and contraction, expanding during heat waves and contracting when it cools down. If these processes are occurring frequently, it can place repeated stress on the pipes, causing them to become loose or burst.
Brisbane can experience extreme heat waves in summer, followed by cooler nights and heavy rain fall. During any time of the year, temperatures can drop quickly from one day to the next. This not only stresses the pipes through thermal expansion and contraction, but heavy rainfall or flooding can also cause soil movement, placing lateral pressure on pipes or allowing them to shift underground.
One bad heat wave, cold spell, or down pour will usually not impact pipes, however, the cumulative effects over the seasons and years can lead to joint fractures, cracks, loosening connections, and full bursts.
Main Types of Pipes and How They Can Fail
Brisbane’s temperatures and climate can impact different pipes in different ways. Damage or leaks can also present differently based on where the pipe is located.
Above-Ground Pipes
Above-ground pipes, such as those running along exterior walls or on top of the ground are exposed to the weather conditions more than underground or internal pipes. These pipes endure hours of direct sunlight, harsh UV exposure, physical impacts, and thermal cycling, stressing the materials and causing the pipes to degrade over time.
During hot days in the direct sun, above-ground pipes can heat up significantly, expanding, then as night falls or the temperature cools, they can cool quickly, causing them to contract. This repeated cycle stresses the pipes over time, causing them to degrade or break.
Fortunately, above-ground pipes are one of the easiest to monitor as they are visible from the surface, and leaks are often obvious. If an above-ground pipe is damaged, there will often be visible damage, leaks, puddles, or water stains.
Underground Pipes
Underground pipes can be particularly problematic, as they’re hidden below the surface. Repeated thermal cycles and soil movement can cause underground pipes to shift, degrade, or break over time. Despite being positioned below the surface, out of direct sunlight, the soil surrounding pipes can still heat and cool, stressing the pipes. Moreover, heavy rain or flooding can promote soil movement around the pipes, allowing them to shift underground and place stress on connections.
When underground pipes become damaged or start to leak it can be slightly more difficult to detect, but there are signs you can look for, such as:
- Unexplained water bill or usage increases
- Puddles or wet patches on the ground
- Sinkholes
- Reduced water pressure
Pipes Inside Structures
Pipes concealed within structures such as walls, ceilings or under floors can be high risk and difficult to detect. If concealed pipes become damaged or start to leak the water can travel long distances within the structure before showing signs, making the origin point difficult to spot.
Fortunately, these pipes are not quite as susceptible to temperature or climate related damage as they are often protected by the structure, however, thermal related damage is not impossible. Repeated cycles can impact pipes within confined spaces over years, especially if they are not properly installed or insulated.
If a concealed pipe becomes damaged, you may notice damp patches or mould growth on walls, ceilings or floors. You may also hear dripping sounds or notice unexplained spikes in water usage or bills. However, it’s important to remember that the leaks can travel long distances, so visible signs can appear a long way from the original issue.
How Professional Pipe Leak Detection Actually Works
Knowing the signs of a pipe leak is important, however, visual inspections alone can only do so much. Identifying whether you have a water leak is the first step to protecting your property, but professional pipe leak detection is essential for accurately locating the source and getting targeted repairs.
As established, water can travel long distances inside structures, underground and above the surface. This not only presents the risk of widespread water damage, but can also make it difficult to pinpoint the cause without specialised methods and expertise.
Professional leak detection teams in Brisbane have years of experience and advanced equipment to quickly and accurately detect and pinpoint leaks in any pipe.
Acoustic Leak Detection
Acoustic leak detection is often the first method used following visual inspections. This method involves using specialised acoustic equipment to scan the ground or structures for the sound of water escaping. This advanced equipment can detect frequencies that the naked ear cannot, allowing us to detect hidden leaks.
This method is best suited for locating leaks within underground or concealed pipework.
Ground Penetrating Radar (GPR) Scanning
Ground penetrating radar, also known as GPR scanning, is also effective for detecting underground voids caused by non-visible pipe leaks or soil movement. GPR scanners use radar pulses to map the subsurface structures without digging, drilling or excavating.
Skilled technicians can use the radar pulses to generate a map of the subsurface and detect where underground pipes are located and whether there has been substantial ground movement. This then allows us to determine whether there is a leak and if so, where it is located.
GPR scanning is also effective for detecting leaks under cement slabs without damage.
Thermal Imaging Detection
Thermal imaging is also effective in detecting hidden leaks. This method uses specialised infrared cameras to detect “hot spots” caused by moisture inside walls or ceilings or under floors.
Water and moisture leave invisible paths inside structures, showing where the water has pooled or travelled. Our technicians conduct thermal imaging of all structures in problem areas to locate any moisture. They can then track the paths to pinpoint the origin point of the leak. This allows for targeted cutting and repairs, ensuring that only the problem area is exposed.
The Real Costs of Leaving a Pipe Leak Undetected
Brisbane’s climate can cause issues at any time, and pipe leaks can cause serious damage and costs if left undetected and unaddressed long-term. Even a small drip can waste hundreds of litres over time, increasing water bills exponentially and causing significant water damage to surrounding structures or movement underground. Moisture can also promote the growth and spread of mould and mildew, leading to serious health risks if breathed in over long periods. This damage can add up over time, leading to extensive and costly structural repairs, excess water charges, and even health conditions.
Early pipe leak detection can help to avoid all of these risks, making it a great investment. Therefore, it’s important to contact a professional leak detection company as soon as you notice any signs.
Address Pipe Leaks As Soon As Possible
From fluctuating temperatures to sustained rainy seasons and flooding, Brisbane’s climate can place significant stress on pipework over time. Whether above-ground, underground, or concealed within structures, pipes can become loose, degrade or burst due to thermal cycles or ground movement, wasting litres of water, costing you dearly, and causing serious damage. Early professional pipe leak detection is the best way to protect your property.
