During our visit, two new gas lines were installed in the backyard. One gas line was installed to the grill. Another gas line was install to the fire pit. Each gas line comes from the gas meter to each fixture. A trench was hand excavated for each gas line, roughly 15-20 feet. After the gas lines were completely installed, they were pumped up with 20 psi of air for 45 minutes to assure there were no leaks. Isolation valves were added at the meter and at the fixtures. Tracer wire was added so each gas line can be located. Each fixture was tested for leaks and functionality after completion. Thanks for choosing Te Certified!!
