During post-rough-in testing, what is the recommended approach to testing and documenting results?

• A. Paint and finish walls first.
• B. Fill and pressurize to code-specified pressure, check all joints and fittings for leaks, and document results.
• C. Skip pressure testing.
• D. Test only with water.

Answer: (B)

Post-rough-in testing is about verifying that the piping system can hold pressure without leaks before walls and finishes are installed. The best approach is to fill and pressurize the system to the pressure specified by code, inspect every joint and fitting for leaks, and document the results with details such as the test pressure, duration, any leaks found, repairs made, and the final status. This sequence ensures leaks are revealed while there’s access to all joints, and the documented record provides evidence of compliance for inspections and future maintenance. Finishing walls beforehand would obscure leaks, and skipping the test or using an incomplete method (like testing only with water) may not meet code requirements or catch all potential issues.
