When is it necessary to perform a pressure test on a gas system?

Performing a pressure test on a gas system is crucial during specific circumstances to ensure the safety and integrity of the system. When a new installation or repair is made, it's essential to conduct a pressure test to verify that all connections, seals, and components are secure and functioning properly. This test helps to detect any potential leaks before the system is put into operation, thereby preventing hazardous situations.

Additionally, if there is a suspicion of a leak, a pressure test is also warranted. This helps confirm whether the gas system remains closed and can indicate any deterioration or failure of parts allowing gas to escape.

Regular use of the system does not necessitate a pressure test; instead, ongoing maintenance and inspections suffice in those cases. Routine inspections themselves are not a substitute for the pressure tests carried out after repairs or installations, as they focus more on evaluating the physical state of components rather than checking for leaks under pressure. Lastly, while some gas systems may have regulatory requirements for periodic inspections or tests (like every five years), this does not specifically refer to pressure tests in all cases, as the timing can be dictated by usage or installation conditions rather than a fixed schedule.
