Sample Plumbing Journeyman practice questions

These sample items mirror the domains in the timed Plumbing Journeyman mock. Correct answers and explanations unlock inside the practice session.

  1. Sample 1

    A helper solvent-welds a 3/4-inch potable adapter into a 2-inch PVC sanitary wye so a lavatory faucet can share the chase. What should the journeyman do?

    • A. Cut it out; keep DWV sanitary piping isolated from potable supply
    • B. Leave it if the adapter is listed for 140°F drain temperature
    • C. Leave it if a dual-check is added on the potable adapter
    • D. Leave it only when the fixture is a water-softener brine tank
  2. Sample 2

    During a restaurant remodel, both a plumbing inspector and a health inspector walk the kitchen. What may the health department specifically regulate?

    • A. Branch circuit wiring for water heaters, pumps, and disposers
    • B. Structural notching and boring limits at plumbing holes
    • C. The utility's rate schedule for municipal water service
    • D. Plumbing sanitation in food sites and public health facilities
  3. Sample 3

    A three-story apartment has long developed length from the heater to distant baths. What does a hot-water recirculation pump do?

    • A. Raise the heater recovery rate so the tank reheats faster after a draw
    • B. Boost cold-water residual pressure at the farthest lavatory on the riser
    • C. Blend cold into the hot loop in place of a thermostatic mixing valve
    • D. Keep hot water moving in the loop so fixtures deliver heat sooner
  4. Sample 4

    A restaurant dining room will have an exposed soil stack. Why might the journeyman choose no-hub cast iron instead of PVC for that run?

    • A. Cast iron damps sound; PVC is lighter and solvent-welded
    • B. PVC is quieter; cast iron is lighter and joined with solvent
    • C. PVC handles higher waste heat; cast iron is limited to dry vents
    • D. Cast iron is solvent-welded; PVC is joined with lead and oakum
  5. Sample 5

    A 4-inch collector in the basement receives the soil stacks and leaves the foundation wall. What is this piping, and where does it end?

    • A. Building sewer, running from the public main to the property line
    • B. Vent header, tying stacks to the roof terminal above the top floor
    • C. Fixture branch, taking each trap arm directly into the soil stack
    • D. Building drain, taking stacks to the sewer just outside the wall
