Q1. A plumbing apprentice is instructed to shut off the water supply before replacing a
faulty valve in a residential system. Which component should be located and closed first to
stop water flow to the entire house?
A. Branch line valve
B. Fixture shutoff valve
C. Main water shutoff valve
D. Pressure relief valve
Correct Answer: 🔵 C. Main water shutoff valve
Explanation: 🟢 The main water shutoff valve controls the entire water supply entering the
building, making it the correct first step for system-wide shutdown. Option A only controls
a section, B controls individual fixtures, and D is used for pressure regulation—not flow
isolation.
, Q2. While cutting PVC pipe, what is the primary reason for deburring the pipe after
cutting?
A. To increase pipe length
B. To reduce friction during installation
C. To prevent blockage and ensure proper flow
D. To change pipe diameter
Correct Answer: 🔵 C. To prevent blockage and ensure proper flow
Explanation: 🟢 Deburring removes rough edges that can trap debris and restrict flow,
ensuring efficiency. A is incorrect as length is unchanged, B is secondary, and D is
unrelated.
Q3. Which tool is most appropriate for tightening a compression fitting on a copper pipe?
A. Pipe wrench
B. Adjustable wrench
C. Hacksaw
D. Tubing cutter
Correct Answer: 🔵 B. Adjustable wrench
Explanation: 🟢 Compression fittings require controlled tightening, best achieved with an
adjustable wrench. Pipe wrenches (A) can damage fittings, while C and D are cutting tools.
