What must be done if a leak or defect is found during testing?

If a leak or defect is found during testing, it is crucial to repair or replace the defective portion and conduct a retest. This action ensures that the system is safe and functioning properly before being returned to service. Addressing leaks or defects immediately helps prevent potential safety hazards such as explosions or toxic gas exposure, which are significant risks associated with LP gas systems. By conducting repairs and subsequent testing, compliance with safety regulations is upheld, ensuring the integrity of the system and protection for individuals and property involved. This proactive approach is essential for maintaining high safety standards in all gas-related operations.
