Domestic water piping is scheduled for enclosure before its required test and inspection. Which sequence is correct?
- ACover it and test only fixtures
- Test and inspect the system before concealment
- CRely on visual joint appearance
- DIncrease final pressure after occupancy for the described plumbing system and documented site conditions
Why B is correct
The best answer is: Test and inspect the system before concealment. Pre-concealment testing finds leaks while joints remain accessible and avoids representing unverified work as complete. The best answer is therefore “Test and inspect the system before concealment.” The other choices either address a different system, rely on an unsafe shortcut, or make a conclusion not supported by the stated facts. The transferred field condition applies the same plumbing design, installation, service, or safety principle to a different project setting. The alternatives omit a prerequisite, conflict with the approved method, or fail to control the stated sanitation or physical hazard.
