Plumbers and pipefitters install and repair pipe systems that carry water, steam, air, or other fluids or gases.

Plumbers and pipefitters determine what materials are needed for a job. They connect pipes and test the pressure to make sure pipe systems are airtight and watertight. They use a variety of tools including:

• Drills
• Saws
• Welding torches
• Drain cleaning tools
• Press fitting tools

Plumbers and pipefitters help develop and review blueprints that show the placement of pipes. They make sure that the plumbing meets building codes.

Plumbers install and repair water, gas, and other piping systems in homes, businesses, and factories. They clean drains, install fixtures such as bathtubs and toilets, and appliances such as dishwashers. They also maintain septic systems for houses.

Pipefitters are sometimes fitters. They install and repair pipes that may carry gas, chemicals, or acids in manufacturing and industrial buildings. Steamfitters are similar to pipefitters but they specialize in systems designed for high pressure liquids and gases.

Plumbers and pipefitters may supervise apprentices and helpers.
