Watermain Leak Detection in Avondale

Leak Locators Ltd regularly services Avondale and the surrounding suburbs, so we know the area well.

Avondale is one of Auckland’s oldest established suburbs, with a history dating back to the mid-1800s. The suburb experienced significant growth following the arrival of the railway in the 1880s and continued expanding throughout the 20th century. As a result, Avondale properties can be served by a wide variety of watermain materials, including galvanised steel, copper and plastic pipework.

Many Avondale homes have undergone renovations and extensions over the years, while the original underground water services have remained in place. This can lead to hidden leaks developing beneath lawns, driveways, footpaths and gardens.

If your water bill has increased unexpectedly and there are no visible signs of a leak around the property, there is a good chance water is escaping from an underground watermain without leaving any obvious surface evidence.

Leak Locators Ltd specialises in locating hidden watermain leaks throughout Avondale and neighbouring suburbs. Whether the leak is beneath a concrete driveway, landscaped garden, retaining wall or shared accessway, we have the equipment and experience to locate it accurately.

Many Avondale properties also have long water service runs from the boundary to the dwelling, making accurate leak detection especially important before excavation begins.

Watermain Leak Detection in Avondale

How We Find Underground Leaks in Avondale

Leak Locators Ltd specialises in locating hidden watermain leaks throughout Avondale, Mt Roskill, Hillsborough, Blockhouse Bay, Mt Eden, Epsom and the surrounding suburbs.

Our first step is to inspect the water meter and determine the approximate age and type of watermain based on the era and style of the property. We then calculate the likely water loss and begin tracing the route of the underground pipe.

Using professional electronic locating equipment, we identify the path of underground services. In many Auckland properties, the watermain was installed in the same trench as power, gas, or telecommunications services, allowing us to establish the most likely route of the pipe.

Once the route has been identified, we use advanced acoustic leak detection equipment to listen for the sound of water escaping from the pipe. Our premium Gutermann leak detection system features a large ground microphone and high-powered amplifiers, giving us the best possible opportunity to locate the leak accurately.

The success of acoustic leak detection can depend on several factors, including:

  • Traffic and construction noise
  • Ground conditions
  • Pipe depth
  • Pipe material
  • Whether the pipe is located beneath concrete or paving

Ferret Leak Locator Technology for Avondale

For difficult leaks, Leak Locators Ltd also uses Ferret Leak Locator technology.

Unlike acoustic equipment, the Ferret pressure-tests the watermain from the inside and is not affected by traffic noise, ground conditions, concrete surfaces, or pipe depth. By testing sections of the pipe individually, the system can accurately determine whether a leak exists within a specific section of watermain.

This technology has successfully located leaks in situations where conventional methods have failed, including:

  • Properties beside busy roads
  • Multi-unit developments
  • Long shared driveways
  • Sites where the route of the watermain is unknown
  • Small leaks that produce little or no detectable sound

Repair or Replace in Avondale?

The most suitable solution often depends on the type and age of the pipe.

Galvanised steel watermains are often nearing the end of their service life and replacement is usually the most practical long-term solution.

Copper watermains can often be repaired successfully, provided the damaged section can be accessed.

Plastic watermains less than 40 years old are frequently excellent candidates for repair, potentially extending the life of the system without the cost of a complete replacement.
