Sample interview questions: Are you familiar with using thermal imaging or infrared technology for identifying hidden drain leaks or defects? If so, can you explain the process?
Sample answer:
Yes, as a professional Plumbing > Drain Technician, I am familiar with using thermal imaging or infrared technology for identifying hidden drain leaks or defects. This advanced technology allows us to detect and locate issues that are not visible to the naked eye.
The process starts with the use of a thermal imaging camera or infrared camera. These cameras work by detecting the infrared radiation emitted by objects. When it comes to drain inspections, we use these cameras to detect any temperature variations in the pipe system.
The first step is to ensure that the area being inspected is at a stable temperature. This is important as any sudden temperature changes can affect the accuracy of the thermal imaging. Once the area is prepared, we can start the inspection process.
The thermal imaging camera is pointed towards the drain system, and it captures the temperature patterns and differences within the pipe network. The camera displays these temperature variations in different colors or shades, allowing us to identify potential leaks or defects.
In a properly functioning drain system, the temperature should be relatively consistent throughout. However, if there is a hidden leak or defect, it can cause temperature variations in the affected area. This can be seen as a colder or warmer spot on the thermal imaging camera display.
