When most people think about plumbers, they usually group them into two large categories, commercial and residential plumbers. However, there is much more to plumbing and many plumbers specialize in specific areas like home remodeling or installing sprinkler systems.

One type of plumber that often gets overlooked is the natural gas line plumber. As the specialty suggests, these plumbers generally work with the installation or repair of natural gas lines. A natural gas plumber can be utilized for the installation or repair of water heaters, HVAC systems, stoves and even outdoor grills.

Usually the plumber will have a license that states he or she is licensed to work on and install natural gas lines. When looking for a plumber to help with a natural gas issue, homeowners should consider whether the plumber has a master plumbing license. The master plumbing license signifies a high degree of experience, qualifications and knowledge regarding the plumbing profession.

John Divine, owner of Charlotte plumbing company, Divine Plumbing, says, "All company owners in the plumbing profession have a master plumbing license. The individuals must pass a state administered exam, pay a license fee and carry liability insurance."
