What must a licensee complete after connecting to piping installed by an unlicensed individual?

A licensee must complete a pressure test to verify the installation rules after connecting to piping installed by an unlicensed individual because this step is critical in ensuring the safety and integrity of the system. Pressure testing helps to identify any leaks or weaknesses in the piping system that may not be immediately visible. This process is essential for confirming that the installation meets the required standards and codes, thereby ensuring safe operation.

By performing a pressure test, the licensee affirms that the piping can handle the intended pressures without failure, which is particularly important when the installation may have been executed without proper licensing or oversight. This safeguard protects not only the immediate surroundings but also the broader community from potential hazards that could arise from improper installation.
