Discovering a leak in your swimming pool can be disheartening and stressful, but with the aid of cutting-edge technology, the process of detection has become more efficient. In this blog post, we will delve into how Thermal Leak Detection and Ultrasonic Leak Detection can help to potentially narrow down and pinpoint the water leak point/s while also acknowledging the importance of a systematic approach to diagnose for swimming pool leaks.
Tell-tale signs of swimming pool leaks
Detecting swimming pool leaks early can prevent costly damage and water loss. Here are some signs to watch for when you are conducting your regular swimming pool maintenance inspection or simply taking a stroll around your swimming pool during your free time:
Decreased swimming pool water level
A noticeable drop in your swimming pool’s water level despite regular refilling could indicate a potential leak or waterproofing issue.
Excessive evaporation
The hot and humid weather in Singapore accelerates the evaporation process, leading to increased water loss from the swimming pool surface. While some level of evaporation is considered normal, unusually high rates of evaporation could indeed signal a potential leak in the swimming pool.
Cracks, loose or damaged tiles
Visible cracks or damages of the pool structure, walls, or floor may indicate a leak. Loose or displaced tiles around the pool perimeter may indicate movement caused by water leaking behind them.
Algae growth
Excessive algae growth despite regular maintenance of the swimming pool might be due to water loss from a leak.
Increased water bills
A sudden increase in water bills with no obvious explanation or tell-tale signs of water seepages around the other parts of the house, could be attributed to a potential swimming pool leak.
Reasons behind swimming pool leaks
Swimming pools can leak for various reasons, ranging from structural issues to equipment malfunctions. Here are some common causes of pool leaks:
Structural damage
Over time, the structure of the pool, including the walls, floor, and joints, can deteriorate due to age, ground movement, or poor construction. This deterioration can lead to cracks or gaps through which water can seep through and damage the underlying waterproofing membrane, resulting in gradual water loss.
Faulty Plumbing
Leaks can occur in the pool’s plumbing system which includes pipes, fittings and valves. These leaks may result from corrosion, joint failures, general wear-and-tear or poor construction workmanship.
Malfunctioning swimming pool equipment
Components of the pool’s filtration and circulation system, such as pumps and filters, can develop leaks due to wear, corrosion, or improper installation as well. It is important to engage a professional swimming pool maintenance contractor to conduct regular checks to ensure all equipment or components are in good conditions.
Damage from tree or plant roots
Tree or plant roots seeking moisture (those in close proximity to the swimming pool perimeter) can infiltrate the swimming pool’s structure or plumbing system, causing cracks or blockages that result in leaks.
Ground settlement
Changes in soil conditions or ground settlement over time can cause the swimming pool structure to settle unevenly, leading to stress on the structure and ultimately resulting in cracks and potential water leaks.
Water Leak Detection Techniques for Swimming Pools
These advanced leak detection techniques can help pinpoint potential water leak points with the help from the right water leakage detection specialist:
Thermal LeakDetect™
Thermal imaging operates by detecting surface temperature differences, which could be indicative of potential water leaks. When water escapes from a pool, it often creates cooler spots on surfaces. The thermal leak detection is conducted to the swimming pool’s walls, floors, and surrounding areas, which may reveal water spots that may be invisible to the naked eye. This allows for more precise identification of leaks in areas that might otherwise go unnoticed.
Limitations
While thermal imaging technology can assist us in detecting potential water leak points, there are certain limitations that require careful attention to maximize accuracy.
In areas with limited temperature differentials, such as shaded or covered sections of the swimming pool, detecting leaks solely through thermal imaging may be challenging. In such cases, employing complementary leak detection methods may be necessary.
While thermal imaging is a valuable tool in leak detection, it is most effective when integrated into a comprehensive strategy that includes other techniques, pressure testing or visual inspection. By combining multiple methods, the likelihood of accurately identifying and addressing leaks is significantly enhanced.
Ultrasonic LeakDetect™
Ultrasonic leak detection is a method that utilizes ultrasonic sensors to detect abnormal or high frequency sound waves emitted along the pipe line which may signify a potential water leak point. In the context of swimming pools, ultrasonic leak detection can be engaged to identify leaks in various components of the pool’s plumbing system, including pressurized pipes installed behind walls, beneath pool surfaces, or within the soil surrounding the swimming pool area.
To conduct ultrasonic leak detection effectively, it’s essential to have a clear understanding of the layout of the pool’s plumbing system, including the location of concealed or underground pipes. By following the pipe plan, water leak detection specialist can systematically scan the suspected areas for signs of abnormal or high-frequency sound frequencies, signifying potential presence of a leak. When the sensor detects a sound pattern consistent with a leak, the water leak detection specialist can mark the location for further investigation and repair.
Limitations
While ultrasonic detection technology can assist us in detecting potential water leak points, certain limitations must also be carefully considered to maximize accuracy.
Despite its effectiveness, ultrasonic leak detection is susceptible to interference from ambient noise levels. Therefore, it is imperative to conduct the inspection in a quiet environment (as much as possible) to ensure optimal results.
For environments with substantial background noise, such as those near industrial facilities, may pose challenges for ultrasonic detectors, potentially compromising their accuracy.
Additionally, the effectiveness of the ultrasonic leak detection may be hindered by absence of pipe plans as well as varying ground construct or depth (such as pebble stones or gravels, soil with grass, etc.). Hence, careful consideration is required during the preliminary discuss and inspection process with clients.
Prompt detection and repair of leaks can prevent further damage to the swimming pool and surrounding property, as well as conserve water and reduce maintenance costs in the long run. While our Thermal Leak Detection and Ultrasonic Leak Detection assist with water leak identification, a systematic approach is essential for comprehensive diagnosis. By combining advanced detection methods and visual inspections, owners can effectively trace and resolve water leakage concerns.
