Sample interview questions: Can you explain your experience with using smoke testing or dye testing to identify drain system defects?
Sample answer:
Smoke Testing
- Conducted smoke testing to detect leaks in extensive drain systems spanning multiple floors and rooms.
- Utilized a smoke machine to introduce non-toxic smoke into the drainage system, which escaped through defects, allowing for precise leak identification.
- Accurately pinpointed leaks in concealed areas, such as behind walls or under floors, minimizing disruption and facilitating targeted repairs.
Dye Testing
- Performed dye testing to assess drainage flow patterns and identify potential blockages.
- Injected colored dye into drain inlets and observed its progression through the system, providing insights into flow dynamics.
- Effectively identified areas of slow drainage, backflow, or stagnation, enabling prompt rectification measure… Read full answer
