Leak Detection

Metallic Pipes

  • We are adept at detecting leaks from pipes that carry products under pressure, be it water, gasoline or a gas product
  • Any liquid or gas will make a noise when leaking from a broken or faulty pipe. For water mains, the water leaving the pipeline at a compromised site generates vibrations, which, when amplified, can be used to pinpoint the leak
  • The success and accuracy of locating any piping depend on several factors: the pipe material, the pressure of the system, the ambient noise level, and the depth of the pipe
  • 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 leakage. 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
  • We use TV cameras to find leaks in sanitary sewers and storm drains

Non Metallic Pipes and Gas Leaks

  • When the pipes are plastic or transite (asbestos cement), a tracer gas is used to help identify the leak location
  • We measure the gas at the surface with a CALIBRATED DETECTOR

Steam, Radiant Heat, and Moisture Testing

  • 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 also moisture test walls and foundations to find concealed leaks

Easy Water Meter Test

This test should be conducted for a 30 minute period, during which water is not being used on the property.

  1. Firstly find your water meter, usually located in front of the house in a covered box near the street.
  2. Write down the numbers indicated on the meter at the start of this test.
  3. Return to check the meter reading after 30 minutes have passed.
  4. 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.
  5. Shut off the valves under all toilets in the house, and repeat steps 1-4.
  6. 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 the water was not being used during the test, and you may need a leak detection service.
