Install pipe assemblies, fittings, valves, appliances such as dishwashers or water heaters, or fixtures such as sinks or toilets, using hand or power tools.

Keep records of work assignments.

Fill pipes or plumbing fixtures with water or air and observe pressure gauges to detect and locate leaks.

Direct helpers engaged in pipe cutting, preassembly, or installation of plumbing systems or components.

Maintain or repair plumbing by replacing defective washers, replacing or mending broken pipes, or opening clogged drains.

Locate and mark the position of pipe installations, connections, passage holes, or fixtures in structures, using measuring instruments such as rulers or levels.

Measure, cut, thread, or bend pipe to required angle, using hand or power tools or machines, such as pipe cutters, pipe-threading machines, or pipe-bending machines.

Anchor steel supports from ceiling joists to hold pipes in place.

Estimate time, material, or labor costs for use in project plans.

Install underground storm, sanitary, or water piping systems, extending piping as needed to connect fixtures and plumbing.

Inspect structures to assess material or equipment needs, to establish the sequence of pipe installations, or to plan installation around obstructions, such as electrical wiring.

Install green plumbing equipment, such as faucet flow restrictors, dual-flush or pressure-assisted flush toilets, or tankless hot water heaters.

Weld small pipes or special piping, using specialized techniques, equipment, or materials, such as computer-assisted welding or microchip fabrication.

Install alternative water sources, such as rainwater harvesting systems or graywater reuse systems.

Recommend energy or water saving products, such as low-flow faucets or shower heads, water-saving toilets, or high-efficiency hot water heaters.

Determine sizing requirements for solar hot water heating systems, taking into account factors such as site orientation, load calculations, or storage capacity requirements.

Perform domestic plumbing audits to identify ways in which customers might reduce consumption of water or energy.

Calculate costs or savings for water- or energy-efficient appliances or systems.

Install, test, or commission solar thermal or solar photovoltaic hot water heating systems.

Compile information on governmental incentive programs related to the installation of energy or water saving plumbing systems or devices.
