The predominant image of a plumber in the average homeowner’s mind is of a tradesman who works on a home’s water and sewer pipes. But plumbers are actually trained to work on gas systems too. This is arguably the most important aspect of plumbing code and training. Gas leaks are everywhere, and under the right conditions they can turn deadly.
Plumbers know how to safely install the various gas piping systems inside the house as well as to locate and repair any gas leaks that develop. Natural Gas is the fuel that keeps about 35% of all Texas homes warm during the winter. Plumbers with the standard Tradesman, Journeyman, and Master licenses are authorized to work on these systems.
However, there is another type of gas used as a heat source in Texas. Although much less common, Propane (LP gas) is used to heat about 3% of homes in Texas.
Historically, the transportation and use of Propane in Texas has been regulated by the Texas Railroad Commission. For this reason, plumbers need an additional registration with the Railroad Commission in order to work on Propane systems and equipment.
Although Propane is very similar to Natural Gas, they are different enough to warrant a separate body of rules that must be followed when installing or working on LP systems.
