Leak Detection in Oregon (Eugene & Portland) and Washington State (Everett, Renton, Seattle, & Tacoma)
CNI Locates provides acoustic underground water leak detection services. We also provide thermal imaging leak detection and tracer gas leak detection services. Thermal imaging leak detection is commonly used for the interior of buildings and can be used in conjunction with other water leak detection services where needed or applicable. Tracer gas leak detection can be used in interior and exterior work areas and is commonly used in conjunction with other underground leak detection services like acoustic leak detection and thermal imaging.
Understanding Acoustic Leak Detection
Underground water leaks in pressurized pipes may make many different sounds:
The “Hiss” or “Whoosh” sound, which often sounds like constant static noise, is the only sound which is always present for water leak detection in pipes with 30 psi or higher water pressure. The other sounds may or may not be present, and usually, they are not as loud. So, we decide, “Is there a leak?” by listening for a “Hiss” or “Whoosh.”
What Factors Affect These Sounds?
How Do Leak Sounds Travel on Pipes?
How Do Leak Sounds Travel Through Soil?
Surveying at a Hydrant and a Service Line:
“Water Leak Pinpointing” is a common term that is applied for the process of pinpointing an exact leak location. For Acoustic Leak Detection, the exact leak location is usually the spot where the leak sounds are the loudest. To find this spot, the leak detection expert must carefully mark the location of the water line in the work area with a pipe and cable locator. Usually, on water mains, the piping between the valve or hydrant with the loudest sound and the valve or hydrant with the second loudest sound is the section of the line that needs to be marked. The section must be accurately located and marked in the area for the leak detection expert to listen directly over the pipe consistently.
Expert technicians at an underground water leak detection company move the ground microphone 2 to 4 feet each time in the direction of the water line, listening and moving closer to the water leak. When a leak detection specialist is moving the microphone, they do not adjust the volume control since the volume control must be held constant to make accurate comparisons. When a leak detection specialist is very close to the leak, it may be impossible to decide, based on the user’s hearing alone, whether the leak is in one spot or 3 to 4 feet away. When this occurs, the leak detection expert must study the visible display (meter) to see if the signal is slightly stronger at one location than at another.

Pool & Spa Tips
The “Bucket Test” will determine if water loss in a pool is due to evaporation or a leak:

Thermal Imaging Leak Detection
Thermal imaging is generally used to locate water leaks in building interiors. Still, it can also complement exterior leak detection methods and help quickly identify leaks or where moisture is gathering. If you need professional leak detection help to find interior leaks, or leaks along windows, roofs, floors, and around the usual water pipes inside your structure, call us today. We can pinpoint leaks and sources before you do any demolition work, saving you time and money.
We can use thermal imaging in conjunction with other water leak locating service applications. When we detect leaks, we think moisture or heat signatures can be useful to help provide a complete picture of your situation.
