Sorry to hear you had problems with your gas installation project, HomeDepotCustomer. It's noted in the Home Flex Design & Installation manual, as well as in instructions included with the product, that the new line be isolated and checked for leaks prior to burial. If leaks are suspected, they can be easily identified via a pressure check (15 psi held for 30 minutes), hissing, and/or soapy solution. If a leak is found, it generally only takes a readjustment of the fitting to make a tight seal. Upon holding pressure, the tracer wire and caution ribbon can be added as the entire assembly is buried.
