If a safety valve is installed, what is its primary function?

• A. To discharge water
• B. To increase pressure
• C. To shut off flow to the suction
• D. To measure flow rate

Answer: (A)

The primary function of a safety valve is to relieve excess system pressure by discharging water. It automatically opens when pressure rises above the set limit, venting water to a safe location and thereby preventing damage to the pump and piping. It remains closed during normal operation and only releases water to lower the pressure, then reseals as pressure drops. The other options don’t fit because this valve is not used to raise pressure, not meant to shut off suction, and not a device for measuring flow rate.
