What should you do if discharge valves or fittings are stiff or frozen?

• A. Do not force them; report to maintenance, and use proper thawing procedures or alternative connections.
• B. Heat with a torch to loosen.
• C. Force them gently until they loosen.
• D. Ignore and continue pumping.

Answer: (A)

Stiff or frozen discharge valves can be damaged if you force them, which can lead to leaks, stripped threads, or ruptured seals. The safe action is not to force them; stop using the discharge, report the condition to maintenance, and follow approved thawing procedures or use alternative connections to keep water flowing. Heating with a torch is unsafe and can damage components or ignite a fuel source, and forcing or ignoring the problem risks larger failures. By using proper thawing methods and, if needed, alternative connections, you protect the equipment and crew.
