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.
- Firstly find your water meter, usually located in front of the house in a covered box near the street.
- Write down the numbers indicated on the meter at the start of this test.
- Return to check the meter reading after 30 minutes have passed.
- 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.
- Shut off the valves under all toilets in the house, and repeat steps 1-4.
- 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.
