Leak detection and repair

What is leak detection?

Leak detection is the process of identifying hidden leaks in pipe systems to prevent costly damage and maintain efficiency. Unlike plumbers who repair pipes, leak detection specialists use advanced tools such as thermal imaging and acoustic sensors to locate leaks with precision and minimal disruption. By addressing leaks proactively, businesses can avoid expensive repairs and ensure peace of mind through expert, non-invasive services.

For a visible, significant water leak, the best practice is to promptly shut off your water supply to prevent further damage. This is done by using the valve near your property’s boundary, typically located next to the water meter and contacting your business water supplier. However, most water leaks are difficult to detect, making regular monitoring of water usage essential for businesses. An unexplained increase in water bills may indicate a leak. To confirm, you can use your water meter by turning off all water-using appliances, recording the meter reading, and waiting a few hours before taking another reading. If the numbers increase, this indicates water loss from a leak. You can calculate the leak rate by subtracting the initial reading from the final one and dividing by the hours elapsed. This method helps identify potential leaks for timely intervention. After identifying signs of a water leak, the next step is to locate the source. If the leak cannot be found, it’s advisable to contact your business water supplier or a professional leak detection contractor who can use advanced technologies to pinpoint the location.

Leak detection professionals use a variety of advanced technologies to identify leaks in commercial properties with minimal disruption. Acoustic and ultrasonic listening devices are used to detect subtle sounds of escaping water, which is particularly useful for identifying leaks in underground pipes or within walls. For pinpointing leaks in hard-to-reach, underground pipes, ground microphones are employed. Thermal imaging cameras are another crucial tool, as they can detect temperature variations caused by water escapes. By scanning walls, ceilings, and floors, these cameras can identify areas where leaks are present,

even if they are not visible to the naked eye. For flat roofs and waterproof membranes, electronic leak detection methods are used to locate leaks accurately. Video pipe inspections involve sending endoscopic cameras through pipes to visually inspect for cracks or damage. In more difficult cases, tracer gas analysis is used, where a harmless gas is introduced into the pipeline and detected at the surface, providing a solution for locating leaks in hard-to-reach areas. Additionally, smart monitoring systems continuously track water usage and flow rates, sending alerts when irregularities are detected, allowing facility managers to respond promptly.

Leak detection and repair process

The leak detection and repair process for commercial properties involves several key steps. It begins with a thorough preliminary assessment, where a professional team meets with the business owner to understand concerns such as water damage, mold, or unusual water usage. Leak detection professionals conduct a comprehensive assessment, with a focus on non-intrusive techniques to minimise disruption to the property.

Next, the leak detection phase involves professionals using advanced tools and techniques to locate the leak. Once the leak is found, the source is identified, with common causes including aging infrastructure, faulty plumbing, high water pressure, or environmental factors.

The repair planning stage follows, where the team develops a tailored solution based on the leak’s location and cause. This may involve pipe repair or replacement, sealing minor leaks, or upgrading plumbing fixtures. Skilled technicians then perform the necessary repairs, ensuring minimal disruption to business operations. If repairs cannot be immediately carried out without causing significant disruption, they are scheduled for a time that minimises the impact. Once the repair is completed, the area is properly dried.

After the repair, a thorough testing phase takes place, including pressure tests and visual inspections, to confirm the leak has been effectively fixed. Finally, maintenance advice is provided to the business, including regular inspections, monitoring of water pressure, and routine maintenance schedules to help prevent future leaks.

There are several measures for preventing commercial water leaks. First, upgrading to a smart water meter allows continuous monitoring of water usage, with alerts notifying you of unusual consumption that may indicate a leak. Additionally, installing water loggers enables businesses to track water use in different parts of the property. Second, regular inspections of plumbing systems, including pipes, taps, and water-using appliances, are essential for detecting early signs of leaks. Plumbing maintenance, such as checking for corroded pipes and worn-out seals, helps prevent future issues. In areas prone to cold weather, insulating external pipes can prevent freezing and bursting. Finally, securing commercial building insurance that covers water leak damage is recommended for added protection.
