What is the primary action taken when a pipe is identified as damaged due to a poor sound test?

When a pipe is identified as damaged due to a poor sound test, the primary action taken is to replace the pipe. This is because a sound test is typically used to assess the integrity of the pipe, and poor results indicate that the pipe may have significant structural issues that could lead to leaks or failures in the water distribution system.

Replacing the pipe ensures that the risk of further damage or problems is mitigated, maintaining the reliability and efficiency of the water distribution system. Repair may not be feasible if the damage is extensive or if the pipe is old, which could result in a recurring issue. Additionally, actions like painting and cleaning are not appropriate responses to structural damage; they do not address the root problem of a compromised pipe and would not ensure the system's long-term functionality.
