What is the purpose of installation of tracer wire with underground piping?

• A. To mark the location of plumbing
• B. To regulate water flow
• C. To identify the type of gas
• D. To prevent freezing of pipes

Answer: (A)

The installation of tracer wire with underground piping serves the important purpose of marking the location of buried plumbing systems. This wire, typically made of a conductive material, is laid alongside underground pipes to provide a means for locating them during future excavation or construction activities. By connecting the tracer wire to the piping system and using specialized equipment, workers can easily detect its presence and position without the need for digging, thereby minimizing the risk of accidental damage to the piping. This practice enhances safety, efficiency, and accuracy in managing underground utilities, particularly in densely populated or developing areas where multiple underground installations may coexist.
