A gas plumber is a professional tradesperson who specialises in the installation and repair of gas plumbing and fittings. This ranges from regulator valves to gas appliances like water heaters and stoves. Due to concerns about the safety of gas, the practice of gas plumbing is regulated by law in many regions of Australia. Gas plumbers must complete an apprenticeship and demonstrate competency skills on an exam before they will be allowed to practice independently as a gas plumber.
Many people generally associate plumbing specifically with water, but in fact plumbing is used to move a wide variety of fluids in addition to gases. Gas plumbers also work with gases used for fuel and heat, such as propane and natural gas. Gas plumbers can install gas tanks or connections to gas mains, along with plumbing in a home which is designed to carry gas, and safety regulators and associated devices. Gas plumbers are also involved in the repair and maintenance of gas lines from those in homes and large businesses, which rely on gas for its day to day operations.
A gas plumber can also work for a municipality, conducting or supervising installations and safety inspections. He or she can also work for a gas company, or as an independent plumbing contractor. A gas-plumbing job requires a very exacting and precise personality, because leaks in gas lines and gas appliances can be deadly in addition to destructive. Gas plumbers need to be familiar with a variety of fittings and important safety procedures and they must be able to identify problems before they happen.
Because gas leaks are such a safety risk and hazard, many regions have gas plumbers who work for emergency services, responding along with firemen and emergency services personnel to the site of a suspected gas leak, or to a fire or explosion caused by gas. Gas companies may also provide twenty four hour service for customers who develop problems with their gas lines, although customers may need to pay for these services
Work for gas plumbers is usually to be fairly steady. New homes being plumbed for gas require the services of a gas plumber, as do structures being retrofitted to accommodate gas, and once gas lines are installed, they need to be regularly and routinely maintained and repaired to reduce the risk of damage, injury, or death. Gas appliances also require maintenance and periodic replacement.
