When should plumbing inspection be called?

The plumbing inspection should be called before supply plumbing is concealed because it is crucial to ensure that all connections, installations, and system configurations are correct and comply with building codes before they are hidden behind walls or other structures. This stage provides an opportunity for a thorough examination of the plumbing work, ensuring that there are no potential issues that could lead to leaks or other problems in the future. Concealing the plumbing prior to inspection would prevent any identification of issues that need correction, leading to costly repairs later on.

This inspection phase allows inspectors to verify that all code requirements are met and that the plumbing system is properly installed and functional before any further construction obscures the system. Essentially, this step safeguards the integrity of the building's plumbing system and promotes compliance with all safety and construction regulations.
