Gas System

The gas system conveys natural gas from the utility gas meter to the individual appliances that need it. This may be a wall furnace, forced air furnace, water heater or kitchen appliances. The system includes the distribution piping (usually black iron or galvanized steel, although corrugated stainless steel tubing CSST is becoming popular) and all of the shut-off valves and flexible supply lines that connect to appliances. Gas systems rarely require expensive repairs, but the need for relatively minor repair is common.
