What is the most common method to verify the field location of a pipe before repair?

The most common method to verify the field location of a pipe before repair is the use of current maps and records. This approach relies on existing documentation, such as municipal or utility maps, engineering blueprints, and previously recorded data about the pipe's layout, including its type, size, and depth. These records often provide the most accurate reference for identifying the underground infrastructure and help determine the exact location of the pipe without the need for invasive methods.

Utilizing maps and records is advantageous because it helps reduce the risk of damaging adjacent utilities while also saving time and resources during the preparation for repairs. This method forms the foundation of pre-repair planning and helps ensure that technicians can approach the repair site with a clear understanding of the layout of existing infrastructure.

While field tests and visual inspections can provide additional context or help confirm findings, they may not offer the comprehensive details that current maps and records provide. Physical excavation, although sometimes necessary, is typically a last resort due to the potential for disruption and the costs associated with digging. Therefore, current maps and records stand out as the most effective and efficient way to accurately verify pipe locations prior to repair.
