Demonstrate the correct sequence for cutting and reaming a steel pipe, including measuring, marking, clamping, and cutting.

List the safety precautions for using a power threader and a portable band saw, and describe the PPE required for each.

Calculate the take-up allowance for a given pipe size and thread type, and explain why it matters for assembly.

Compare solvent-welded PVC, soldered copper, and threaded steel joints in terms of tools, materials, and safety hazards.

Practice making a solvent-welded PVC joint and a soldered copper joint under supervision, following the correct procedure for each.

Identify common defects in each joint type and explain how to avoid them.

Select the correct abrasive, flux, and solder for a given copper tube size and application.

Interpret the symbols and line types used on a typical plumbing floor plan, riser diagram, and isometric drawing.

Extract the pipe sizes, fittings, and fixtures from a simple plumbing drawing and list them in a take-off table.

Measure and mark pipe runs on a wall or floor according to a given drawing, using a tape measure and level.

Calculate the total length of pipe required for a small bathroom group, including allowances for fittings and waste.

Describe the purpose and function of vents, traps, and cleanouts in a drainage system.

Explain the difference between a wet vent and a dry vent, and identify where each is permitted.

Identify the hazards of working in a trench and list the steps to take before entering an excavation.

Demonstrate the correct use of a gas monitor and explain the action levels for oxygen and hydrogen sulfide.

Communicate a technical issue to a supervisor or client in plain language, both verbally and in writing.

Identify the safety data sheet (SDS) information for a common plumbing chemical and describe the first-aid measures.

Use a level, plumb bob, and laser level to establish grade and alignment for a drainage run.

Calculate the fall required for a given pipe length and diameter to achieve the correct slope.

Measure and cut pipe supports and hangers to the correct length, and install them at the required spacing.

Demonstrate the safe use of a hammer drill to anchor supports to masonry.

Assemble a mock-up of a water supply and drainage system that includes at least one fixture, one vent, and one cleanout.

Pressure-test the water supply system and perform a flow test on the drainage system.

Identify and correct any leaks or code violations in the mock-up.

Review the entire study plan and list three areas where you need further practice.
