Most residential gas line work comes with an upgrade: a tankless water heater, a gas range or a new dryer. Each needs a correctly sized line, a shutoff valve and a leak test.
Gas work is not a DIY job. It is licensed and permitted in North Carolina for good reason.

Gas Line Services FAQs
What should I do if I smell gas?
Leave the building without operating switches, then call the gas utility or 911 from outside.
Does a tankless water heater need a bigger gas line?
Often. Tankless units can demand more gas than a tank heater, so the line is checked and upsized if needed.
