If your water bill has been steadily increasing and you suspect a leak, you can check your water meter indicator for movement. This is located in the meter box and requires removing the lid. Wait 1 or 2 hours without using any water and check the meter reading again.

NDT is a broad term that describes any non-intrusive method used to evaluate the integrity of a product or weld. It covers a wide range of techniques that do not affect the properties of the object being tested, such as noise tests (sound waves), radiographic inspections (x-rays or gamma radiation) and magnetic particle testing (using an electric current and magnets to detect surface and subsurface flaws). NDT is also known by the more technical names of non-destructive evaluation, non-destructive analysis and non-destructive examination.
NDT can be useful in any industry that deals with a product that needs regular maintenance and checking. It is particularly important for companies that need to comply with certain regulatory standards, such as airlines or oil and gas companies. Compliance with these standards can be expensive if companies fail to meet them, so there is a strong incentive for companies to use NDT whenever possible.
The main advantage of NDT is that it does not damage the product or structure being tested. This is because the NDT technique does not change the material being tested, for example by applying heat, pressure or chemicals. It also does not leave behind any scars or dents, which can be caused by conventional destructive methods.
Different NDT methods are used for different applications, depending on the type of material and its thickness. For instance, ultrasonic NDT uses high-frequency sound waves to detect internal flaws in a material. It is a common method for inspecting boilers and turbines in power plants, as well as for detecting leaks.
X-ray and gamma radiation are used for radiographic NDT, which involves looking at the material’s internal structure. These are commonly used in nuclear power plants and for the inspection of oil pipelines. These tests can spot defects and flaws in metals, but they cannot see through some materials such as glass or plastics.
Magnetic particle inspection is another popular form of NDT, detecting flaws by using an electric current and magnetic fields. This method is usually carried out by an experienced engineer, and it can be used to examine a wide variety of materials and structures, from cast iron pipes to ferromagnetic tools.
Sonic leak detection
Sonic leak detection works much like acoustic water leak detection, but instead of listening for sounds created by water leaks, it listens for sound generated from pressurised systems. Highly pressurised gas leaks emit a distinctive hiss that sonic sensors can pick up, even when there are other sources of noise present in the same area. This makes the process of locating the source of a leak much faster and easier.
A sonic gas detector is an electronic instrument that measures the concentration of methane or other dangerous gases in the air. This instrument is usually mounted in a fixed location and is connected to a monitor, which displays the gas levels and can be configured to trigger an alarm or other notifications in case of an unusual reading. These devices can also be integrated with Smart Home technology to shut off the gas supply to your home if it detects a leak in one of your appliances.
These sonic leak detection tools are very similar to ultrasonic microphones, but they convert the acoustic signal to a digital readout that can be displayed on a screen or viewed through a set of headphones. They can be used to scan for the hissing of a pressurised leak or for holes in containers, cars and yachts. They are also ideal for detecting electrical arcing* which can break insulation and cause a fire.
Many sonic leak detection systems require professional installation and involve alteration to the plumbing in your home, so it is recommended that you hire a licensed plumber to ensure that this type of system is correctly installed. However, there are simpler systems that monitor your home’s plumbing without requiring any modification to your home’s water pipes.
Most sonic leak detection systems come with a pair of headphones that allow incoming sound emissions to be heard and interfering noise to be blocked out. It is important to use these headphones, as the device will only work properly if it can accurately discern between a leak and other sounds that may be occurring in your home, such as rushing water or a television.
LiDAR
LiDAR is a powerful technology for detecting methane leaks from pipelines. By sending laser pulses to reflect off objects, it can accurately measure the distance between points on the ground, generating detailed 3D representations of an area. This information can be used to pinpoint the source of a leak, allowing engineers to quickly respond and prevent damage or other consequences. While this method isn’t as fast as sonic leak detection, it offers much higher accuracy than traditional methods.
There are several types of LiDAR systems available, each with its own advantages and disadvantages. For example, mechanical LiDAR systems rely on rotating mirrors or other mechanical components to direct laser beams across the landscape. This allows for a wider field of view, but introduces a number of points of failure. This type of system is best suited for applications with long range capabilities and large spatial coverage.
In contrast, digital LiDAR systems rely on software algorithms to process and analyze laser signals, providing high-resolution spatial data for mapping terrain and objects. This technique eliminates the need for physical movement, resulting in greater efficiency and accuracy. It can also be integrated with a camera to provide immersive 3D visualizations of the landscape.
The resolution of LiDAR data determines how finely the laser beam is sampled, resulting in a more or less detailed representation of the environment. The optimal balance between resolution and accuracy depends on the needs of the project. For example, a lower resolution can be sufficient for tasks that require basic topographic mapping and obstacle detection, while a higher resolution can be more useful for complex mapping or visual identification of specific features.
Natural gas pipeline companies use LiDAR to locate methane leaks in their right of way. This technology enables them to save time and money by reducing the number of on-site surveys. In addition, it reduces environmental risks by minimizing the need for excavations. This technique also improves safety by identifying leaking methane before it can reach the water table and cause contamination.
Thermal imaging
Thermal imaging works by converting infrared radiation (heat energy) into a visual image. It can detect objects and surfaces that are warmer or cooler than their surroundings. This technology can be used in a variety of applications, from military and law enforcement to healthcare and home inspections. Thermal imaging cameras use a special sensor called a microbolometer, which measures the thermal radiation emitted by an object. The sensor then converts the measurement into an electrical signal, which is then converted to a visual display on a screen or monitor. Microbolometers are small and don’t require complex cooling systems, which makes them ideal for handheld and portable devices such as thermal imaging cameras.
Professional leak detection companies will use a thermal imaging camera as part of their equipment to help locate water leaks in your property. The thermal image allows plumbers to pinpoint the exact location of a leak, reducing the amount of time and labour needed to carry out repairs. The thermal image also minimises the area that needs to be cut into, resulting in lower repair costs for homeowners.
Water leaks can cause a wide range of problems, from structural damage to health hazards and increased energy bills. It is important to act quickly when you suspect a water leak, to prevent the situation from worsening. Thermal imaging is one of the fastest and most effective methods of leak detection, helping professionals to identify problem areas and plan appropriate actions.
The technology is particularly useful for detecting hot water leaks as escaping water causes the surrounding surface to cool down, making it easier for the cameras to detect. However, thermal imaging cannot find all leaks and should be complemented with other detection methods such as acoustic leak detection or tracer gas.
It is important to prepare for a thermal scan by moving any furniture away from walls and removing any drapes or blinds. This will ensure the most accurate reading possible, and make the process less disruptive to your home. Additionally, a thermal scan is most effective during winter when indoor temperatures are typically higher than outdoor temperatures.
