I installed a 1 1/2" gas line. The City Inspectorate told me to test the new gas line to three times the suggested gas pressure within 24 hours. This article got the job done. While ordering a new pad I'm pretty sure this item wasn't 'new' but it did what it was supposed to do, son can now use it for his house construction.
