Metallic Pipes

Leaks from pressured water mains are readily located using acoustic leak detecting instruments. The water leaving the pipe at a leak generates vibrations, which when amplified, can be used to pinpoint the leak. The success and accuracy of any locate depends on several factors: the pipe material, the pressure of the system, the ambient noise level and the depth of the pipe.

Non Metallic Pipes and Gas Leaks

In some cases, especially when the pipes are plastic or transite (asbestos cement), a tracer gas is used to help identify the leak location. The gas is detected on the surface with a CALIBRATED DETECTOR.

Easy Water Meter Test
1. This test should be conducted for a 30 minute period, during which time no water is being used on the property.
2. Find your water meter, which is usually located in front of the house in a covered box near the street.
3. Write down the numbers indicated on the meter at the start of this test.
4. Return to check the meter reading after 30 minutes have passed.
5. If the numbers have not changed, you do not have a leak in your pressurized water system. If the numbers have changed, continue with the following steps.
6. Shut off the valves under all toilets in the house, and repeat steps 1-4.
7. If the numbers have not changed, you may have a running toilet that should be serviced.If the numbers have changed, this indicates water consumption even though water was not being used during the test, and you may need a leak detection service.

Leak Detection 1Leak Noise Correlation

Leaks in metallic pipes may be detected using a leak noise correlator. This computerized instrument uses two microphones and amplifiers placed at valves in the vicinity of the leak. These microphones transmit the vibrations from the leak to the processing unit which, when fed the pipe material and length between microphones, indicates on screen where the leak is located in relation to the valves. In a system wide survey microphones can be moved from valve to valve checking each pipe length or city block for the presence of leaks. Subtronic utilizes the latest developments in acoustic leak detection technology and employs leak noise correlations, numerous tracer gas detections, leak detecting “pigs” with radio transmitters and TV cameras to find leaks in sanitary sewers and storm drains.

Steam, Radiant Heat and Moisture Testing
In addition to finding leaks in water and gas pipes, Subtronic can also locate leaks in steam and radiant heating systems. Using a combination of infra-red technologies, noise correlation and line locating Subtronic can accurately pinpoint the location of most leaks. Subtronic can also moisture test walls and foundations to find concealed leaks.
