Which of the following indicates a likely need for repair in distribution pipes?

The identification of bulging or pinholes in the pipe material is a clear indicator of a likely need for repair in distribution pipes. These physical deformities often suggest that the pipe has been compromised, which may lead to leakage and other significant issues down the line. Bulging indicates that internal pressure may be exceeding what the pipe material can handle, while pinholes suggest that corrosion or wear has created weak points that could lead to potential failure.

Regular maintenance checks generally serve to prevent issues rather than indicate a need for immediate repair, and consistent water pressure typically reflects a well-functioning system. Recent installation of joints may signify that the pipe system has been updated or repaired appropriately; thus, it does not imply a current issue. The presence of bulging or pinholes, however, is a direct sign of physical damage that must be addressed to avoid further deterioration and maintain the integrity of the distribution system.
