  •  High Water Bills: Unexpectedly high water bills are a common sign of a leak in your mains water supply.
  • Water Meter Activity: A constantly spinning water meter, even when no water is being used, indicates a possible leak.
  • Supplier Notification: Water suppliers may issue a Section 75 Notice if they detect a leak on your property.

How Do You Do Mains Water Leak Detection?

Acoustic Microphone

An acoustic microphone is a sophisticated device used to listen for the sound of water escaping from pipes. By capturing these sounds, our technicians can pinpoint the exact location of a leak with high precision. This method is non-invasive and highly effective, making it a preferred choice for leak detection.

Gas Tracing

Gas tracing involves injecting a harmless tracer gas into the mains water pipe. Sensitive probes then detect the gas as it escapes from the leak site. This technique allows us to accurately locate leaks, even those that are deeply buried or in hard-to-reach areas. Gas tracing is particularly useful for identifying leaks that are not easily detectable by other means.

Moisture Meters

Moisture meters are essential tools for identifying hidden leaks. These devices measure the level of dampness in walls, floors, and other structural components. By mapping areas of excessive moisture, we can determine the presence and extent of leaks, even when there are no visible signs of water damage.

Endoscopic Cameras

Endoscopic cameras provide a visual inspection of pipes within walls, floors, and other inaccessible areas. These cameras are flexible and can navigate through the piping system, offering a clear view of the interior condition. This method is invaluable for confirming the exact location of a leak without causing extensive damage to the property.

Combining Methods for Accuracy

At Dorset County Water, we often combine these advanced techniques to ensure the most accurate and efficient leaking pipe or mains water leak detection. By using a combination of acoustic microphones, gas tracing, moisture meters, and endoscopic cameras, we can provide a comprehensive assessment and promptly address any leaks.

How to Prevent Water Leaks

Regular Inspections: Regular inspections are crucial for maintaining the integrity of your water supply system. Schedule professional inspections at least once a year to check for signs of wear and tear, corrosion, and potential leaks. During these inspections, experts will examine all accessible pipes, joints, and fixtures, ensuring any issues are identified early before they escalate into significant problems. Additionally, frequent self-inspections can help you spot unusual dampness, rust, or puddles, which could indicate a developing leak.

Leak Detectors: Installing electronic leak detectors is a proactive way to manage water leaks. These devices are designed to alert you immediately when a leak is detected, allowing for a quick response to minimize damage. There are several types of leak detectors available:

  • Standalone Detectors: These can be placed near potential leak sources such as sinks, toilets, and water heaters.
  • Inline Detectors: Installed directly into the plumbing system, these detectors monitor water flow and can shut off the water supply if a leak is detected.
  • Smart Detectors: These connect to your home network and send alerts to your smartphone, providing real-time updates and remote control over your water system.

Maintain Water Pressure: Maintaining the proper water pressure in your home is essential for preventing leaks. High water pressure can put excessive strain on pipes, joints, and fixtures, leading to leaks and bursts. To ensure your water pressure is within the recommended levels:

  • Install a Pressure Regulator: This device automatically adjusts the water pressure entering your home, keeping it at a safe level.
  • Regularly Check Pressure Levels: Use a pressure gauge to monitor your water pressure periodically. Ideal residential water pressure typically ranges from 40 to 60 psi.
    Adjust as Needed: If the pressure is too high or too low, adjust the pressure regulator or contact a professional to make the necessary adjustments.

By following these preventive measures, you can significantly reduce the risk of water leaks, protecting your property and ensuring a reliable water supply.

Our experienced mains water leak detection team is here to help you keep your water supply system in top condition.

Repairing a Mains Water Leak

When it comes to repairing a leaking water main, the first step to take is to shut off the water supply immediately. This crucial action helps prevent further water loss and minimizes potential damage to surrounding areas.

Following the initial isolation of the affected section, temporary measures should be implemented to mitigate any immediate risks. For example, applying waterproof tape or using a clamp to seal the leak can provide a temporary fix until more permanent repairs can be arranged.

Once the leak is temporarily contained, the next phase involves considering permanent solutions. This typically includes replacing damaged sections of the pipe to ensure a lasting repair. For minor leaks, applying specialized sealants designed for plumbing repairs can also be effective in preventing water seepage.

In cases where the leak is complex or extensive, it’s advisable to seek professional assistance from experienced mains water leak detection specialists. They can assess the situation thoroughly and perform repairs that adhere to industry standards, thereby minimizing the likelihood of future issues.

After completing the repairs, conducting a comprehensive system test is essential. This final step verifies that the leak has been properly addressed and ensures the overall integrity of the plumbing system.
