What is the name of the plumbing inspection conducted before covering walls and floors?

• A. Rough-In Inspection
• B. Final Inspection
• C. Pressure test
• D. Site Inspection

Answer: (A)

Before walls and floors are covered, the plumbing work is checked through a rough-in inspection. This stage focuses on the basic layout and installation of piping, drains, vents, traps, and related fittings to ensure everything is placed correctly and installed to code. It verifies that pipe sizes and slopes will allow proper drainage, that venting is correctly arranged to prevent siphoning, and that cleanouts and connections to the main stack are positioned where they should be for accessibility and future maintenance. This inspection confirms that the concealed portions of the system are sound and that the project can be closed in without risking leaks or improper operation. Final inspection, by contrast, happens after all work is completed, including fixtures and finishing touches, to confirm everything functions properly and complies with code in the finished state. A pressure test is a leak test used to check for integrity of the piping, and while it may be performed during rough-in, it is a test, not the name of the inspection itself.
