Watermain Leak Detection in Hillsborough
Leak Locators Ltd regularly services Hillsborough and the surrounding suburbs, so we know the area well.
Hillsborough is one of Auckland’s most established suburbs, with a mix of older character homes, post-war housing and modern developments. Many properties are located on steep sections overlooking the Manukau Harbour, often with long driveways, retaining walls and underground services that can make leak detection particularly challenging.

The suburb takes its name from James Carlton Hill and is home to some of Auckland’s most notable historic landmarks, including the Pah Homestead and Monte Cecilia Park. As Hillsborough developed through the 1950s, 1960s and beyond, a variety of watermain materials were installed, including galvanised steel, copper and plastic pipework.
If your water bill has increased unexpectedly and there are no visible signs of a leak, there is a good chance water is escaping from an underground watermain beneath your lawn, driveway or paved areas.
Leak Locators Ltd specialises in locating hidden watermain leaks throughout Hillsborough and neighbouring suburbs. Whether the leak is beneath a concrete driveway, retaining wall, garden or shared accessway, we have the equipment and experience to locate it accurately.
How We Find Underground Leaks in Hillsborough
Leak Locators Ltd specialises in locating hidden watermain leaks throughout Lynfield, 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 Hillsborough
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 Hillsborough?
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.
