When passing through a wood stud, PVC plastic pipe shall be protected from puncture by a minimum _______ inch thick steel plate.

The requirement for PVC plastic pipe to be protected from puncture by a minimum thickness of a steel plate is to ensure the integrity of the pipe when it is installed within walls or other structural elements. When passing through a wood stud, a steel plate serves as a protective barrier that prevents any fasteners, like nails or screws, from penetrating the pipe and causing a leak or failure.

In this case, the minimum thickness of 1/16 inch is sufficient to provide the necessary protection for PVC pipes. This thickness is standard because it balances adequate protection without adding excessive cost or difficulty in installation. The thin plate can withstand incidental contact while remaining practical for typical construction scenarios. Understanding this requirement is crucial for compliance with safety codes and ensuring the longevity of plumbing installations.
