What should you do after successfully repairing a pipe?

After successfully repairing a pipe, it is essential to conduct an operational test to check for leaks. This step is crucial because it verifies the integrity of the repair and ensures that there are no ongoing leaks which could lead to further damage, undermine the efficacy of the repair, or pose safety hazards. An operational test typically involves pressurizing the system to the normal operating levels and monitoring for any signs of leakage. This process helps to confirm that the repair was successful and that the pipe is functioning as intended.

While other options may seem reasonable, such as inspecting every joint or leaving the repair alone, they do not directly address the immediate need for verification after a repair. Painting over a repair without first testing for leaks could mask any issues and potentially lead to serious problems if the repair fails under pressure. Thus, performing an operational test is the most appropriate and effective step following a pipe repair.
