What is the minimum requirement before a plumbing system is covered?

The minimum requirement before a plumbing system is covered is inspection and testing. This is a crucial step in the plumbing process because it ensures that the system has been installed correctly and is functioning as intended before any wall coverings or flooring are put in place. By conducting thorough inspections and tests, the plumber can verify that there are no leaks, that all joints and connections are properly sealed, and that the system meets the necessary codes and regulations. This helps to prevent issues that would be much more difficult and costly to address after the plumbing has been covered up. Therefore, inspection and testing serve as a safeguard to ensure the integrity and reliability of the plumbing system, ultimately protecting the health and safety of the occupants.
