These sample items mirror the domains in the timed Plumbing Journeyman mock. Correct answers and explanations unlock inside the practice session.
Sample 1

- D. Plumbing sanitation in food sites and public health facilities
Sample 3
A three-story apartment has long developed length from the heater to distant baths. What does a hot-water recirculation pump do?
