Whether a plumbing installation passes or fails an inspection is subject to a code officer’s interpretation. You can appeal a decision that you feel is incorrect or questionable. Even as a master plumber your understanding of the intent of the code is not absolute. The plumbing inspector is the final word in the field when it comes to an interpretation of the code.
