ball valves.
butterfly valves.
post indicator valves.
outside stem and yoke valves.

the weekly inspection of a fire pump is a good time to ensure that:

the diesel fuel tank is at least one-quarter full.
there is enough water in the fuel tank.
the batteries are at least 50% charged.
all control valves that are to be open are open and supervised in the open position.

Explanation:

Analyze the first question

The first question asks about the type of indicating control valves required on the supply side of a horizontal split-case fire pump. According to NFPA 20 (Standard for the Installation of Stationary Pumps for Fire Protection), indicating control valves on the suction (supply) side of a fire pump must be of the outside screw and yoke (OS&Y) type. This is to ensure that the valve's open or closed status is visually obvious from a distance and to prevent turbulence that could damage the pump.

Analyze the second question

The second question asks about the purpose of the weekly inspection of a fire pump. According to NFPA 25 (Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems), weekly inspections are critical to verify that the system is in an operative condition. A key component of this is ensuring that all control valves that are supposed to be open are indeed open and properly supervised, preventing accidental water supply shutoffs.

Answer:

Question 1

• ball valves.
• butterfly valves.
• post indicator valves.
• outside stem and yoke valves. (Correct answer)

Question 2

• the diesel fuel tank is at least one-quarter full.
• there is enough water in the fuel tank.
• the batteries are at least 50% charged.
• all control valves that are to be open are open and supervised in the open position. (Correct answer)
