INTRODUCTION
The Alabama Journeyman Plumber Examination is designed to assess the knowledge, skills, and
competency of candidates seeking licensure as journeyman plumbers in the state of Alabama. This
comprehensive examination evaluates understanding of plumbing codes, drainage systems, water supply,
fixtures, and safety protocols. The test employs multiple-choice and scenario-based questions to measure
both theoretical knowledge and practical application. Emphasis is placed on real-world problem-solving,
code compliance, and professional decision-making to ensure candidates are prepared to perform
plumbing work safely and effectively while protecting public health and safety.
SECTION ONE – QUESTIONS 1–100
Question 1
,What is the primary purpose of the International Plumbing Code (IPC)?
A. To set industry standards for manufacturing plumbing fixtures
B. To establish minimum requirements for plumbing design, installation, and safety
C. To regulate the sale of plumbing supplies
D. To provide specifications for plumbing tool manufacturing
🟢 B. To establish minimum requirements for plumbing design, installation, and safety
🔴 Explanation: The IPC provides minimum standards for plumbing systems to ensure safety, health,
and efficiency in design and installation. It serves as the governing code for plumbing work in
jurisdictions that adopt it, including Alabama.
Question 2
Which pipe fitting creates a tight seal using a compression ring and nut?
A. Coupling
B. Flange
C. Compression fitting
D. Union
🟢 C. Compression fitting
🔴 Explanation: Compression fittings use a compression ring and nut to create a tight, leak-proof seal
on pipes. They are commonly used for connecting copper tubing and are particularly useful in tight
spaces where soldering is impractical.
Question 3
Who holds overall responsibility for ensuring that plumbing work on a project complies with all
applicable codes?
A. The building owner
B. The master plumber
C. The city inspector
D. The homeowner
,🟢 B. The master plumber
🔴 Explanation: The master plumber holds overall responsibility for code compliance and proper
installation of plumbing systems. While inspectors verify compliance, the licensed professional
performing or supervising the work bears primary responsibility.
Question 4
What does DWV stand for in plumbing terminology?
A. Drinking Water Valve
B. Drainage, Waste, and Vent
C. Domestic Water Volume
D. Direct Water Venting
🟢 B. Drainage, Waste, and Vent
🔴 Explanation: DWV refers to the system that manages drainage, waste removal, and venting in
plumbing. This system is foundational to sanitary plumbing and ensures proper removal of wastewater
while preventing sewer gases from entering occupied spaces.
Question 5
What is the minimum slope typically required for horizontal drainage piping of 3 inches or larger?
A. 1/8 inch per foot
B. 1/4 inch per foot
C. 1/2 inch per foot
D. 1 inch per foot
🟢 A. 1/8 inch per foot
🔴 Explanation: Per IPC Section 704.1, horizontal drainage pipes 3 inches and larger must have a
minimum slope of 1/8 inch per foot. Pipes smaller than 3 inches require a steeper slope of 1/4 inch per
foot to maintain self-cleaning velocity.
Question 6
, Which tool is specifically designed for cutting copper tubing with clean, square edges?
A. Pipe wrench
B. Tubing cutter
C. Hacksaw
D. Reciprocating saw
🟢 B. Tubing cutter
🔴 Explanation: A tubing cutter provides smooth, clean cuts on copper tubing without crushing or
deforming the pipe. It creates a square edge essential for proper soldering and fitting installation.
Question 7
What is the primary function of a plumbing vent system?
A. Increase water pressure
B. Prevent sewer gases from entering the building
C. Speed up drainage flow
D. Reduce pipe size requirements
🟢 B. Prevent sewer gases from entering the building
🔴 Explanation: Vent systems allow air into the drainage system and prevent sewer gases from
entering occupied spaces while maintaining proper trap seals. They equalize air pressure in drainage
pipes, preventing trap siphonage.
Question 8
Which fixture is typically connected to a trap to prevent sewer gases from entering a building?
A. Water heater
B. Toilet or sink
C. Water softener
D. Pressure regulator
🟢 B. Toilet or sink
