These are the steps we take to find a concrete slab or exterior pipe leak/break.
Step 1:
Using a Flir camera, look for thermal anomalies under the concrete slab. FLIR stands for forward-looking infrared. When pointed at the slab, the camera produces a video image based on temperature instead of light used in a standard camera.
Step 2:
Pipe locating. Soft copper or metal pipe. We use Radio Detection pipe locating equipment dialed into 512 Hz frequency to pinpoint the exact location of the pipe leak.
Step 3:
Listen for the leak. To go a step further, we listen to a designated area with our microphone equipment that has sophisticated filters and noise-canceling abilities if working in a noisy environment. This state-of-the-art equipment helps us further identify the location of the leak.
Step 4:
Inject air into the system for a precise pinpoint of the location. For this, we usually use a dive tank and inject air into the system at very low pressures. As the air exits the pipe through the hole, it produces a loud bubbling noise, making it easier to dial in on the exact location of the leak.
Our Methods:
For outdoor leaks, we can inject hydrogen gas and use special sniffers to find the gas when the pipe is too deep to hear the actual leak. Locating plastic PVC pipe. One method when you have a large pipe is to inject a special conductive prod. We then attach the signal generator to one of the rods, and we can walk out of the pipe’s path with our regular metal pipe locator. Another method is to have someone tap on one end of the pipe and attempt to locate the echoing of the sound as it goes down the pipe with our sophisticated microphones.
