How often should gas line pressure tests be performed?

Testing gas line pressure is a critical safety measure in ensuring the integrity of the gas distribution system. Conducting pressure tests during the installation of the gas lines helps verify that there are no leaks and that the system is functioning correctly before it becomes operational. This initial testing is essential to establish a safe environment for future users.

Additionally, performing pressure tests after any repairs is equally important. Repairs can alter the integrity of the gas lines, and a pressure test will confirm whether the repair was successful and that the system remains leak-free post-maintenance. Acceptance for service is only appropriate when the lines have passed these tests, providing assurance that the installation is safe and compliant with relevant codes.

While annual tests and inspections with the addition of new appliances are important for ongoing safety and compliance, they do not substitute the essential practice of testing after installations and repairs.
