What are the functions of a hydrant wrench and a strainer during pumping operations?

• A. Wrench opens/closes hydrants; Strainer prevents debris entering pumps during drafting or priming.
• B. Wrench tightens hoses; Strainer increases water flow.
• C. Wrench locks vehicles; Strainer collects debris.
• D. Wrench helps carry hoses; Strainer prevents leaks.

Answer: (A)

In pumping operations, you need to both access the water source and protect the pump from debris. The hydrant wrench is the tool used to operate fire hydrants—turning the hydrant’s operating nut to open or close the valve and start or stop the water flow. The strainer is placed on the pump intake during drafting or priming to screen out debris, preventing it from being pulled into the pump and potentially clogging parts or losing prime.

This pairing makes sense because it covers two essential tasks: getting water from a hydrant and keeping the pump protected from contaminants. The other options describe functions that don’t match these tools—for example, tightening hoses, increasing flow, locking vehicles, carrying hoses, or preventing leaks.
