Gas plumbing is anything that has to do with the installation and maintenance of natural gas lines and pipes for homes and businesses. Some of the most common gas plumbing projects are for water heaters, fireplaces, stoves, outdoor grills and various other heating, ventilating and air conditioning systems.
Gas plumbers require a special certification in the field, and the most qualified professionals hold a master plumbing license that signifies their qualifications in all fields of plumbing.
Some of the most common materials used for gas plumbing include black iron and corrugated stainless steel. Before installing piping, natural gas plumbers must look at the British thermal unit output of the appliance they are connecting before determining the size of piping needed. Some natural gas plumbers also work with propane connections.
