Journeyman Plumber ExamTools, Equipment, and SafetyMedium
A journeyman plumber is tasked with removing a corroded galvanized steel union that has seized. The union is in a tight space, making it difficult to apply significant leverage. Which of the following tools is best suited for breaking loose the seized union without damaging adjacent piping or fittings?
- ABasin wrench
- BChain wrench
- CPipe wrench
- DAdjustable wrench
Show answer & explanationAnswer & explanation
Correct answer: C. Pipe wrench
A pipe wrench, with its serrated jaws and adjustable leverage, is specifically designed for gripping and turning round pipes and fittings, making it ideal for breaking loose seized unions. Its strong grip prevents slipping, which is crucial when dealing with corroded components.
Why the other options are wrong
- A. A basin wrench is designed for faucet nuts in tight spaces, not for the heavy torque required to loosen seized pipe unions.
- B. A chain wrench is used for larger diameter pipes and fittings, and while it provides grip, a pipe wrench is more appropriate for standard union sizes.
- D. An adjustable wrench is not designed for the heavy-duty grip required for seized pipe fittings and can slip, causing injury or damage.
Pipe Wrench
A pipe wrench is a heavy-duty adjustable wrench used for turning and holding pipes and pipe fittings, especially those that are corroded or seized.
- Features serrated, adjustable jaws for a strong grip.
- Designed for round pipes and fittings.
- Provides high leverage for loosening tight connections.
Memory trick: Pipes always need a strong GRIP to twist free.
