Under what condition may the code official allow a temporary connection to the utility source?

The code official may allow a temporary connection to the utility source primarily for testing plumbing systems. This is important because testing ensures that all components are functioning correctly, helping identify any leaks or failures before the system is fully operational. Testing is a critical step to ensure safety and compliance with building codes, as it verifies that the plumbing installation meets the required standards.

Temporary connections for testing purposes are carefully regulated to maintain the integrity of the system and ensure public health and safety while construction or installation processes are underway. Test connections must be done under controlled conditions to prevent any adverse effects on the utility system or surrounding environment.

This rationale affirms the need for strict adherence to plumbing codes and helps ensure that the plumbing system will operate safely and efficiently once it is permanently connected and in use.
