What should be tested to verify that the installation is correct for pressure regulating devices?

• A. Pressure setting accuracy
• B. Relief valve operation
• C. All of the above
• D. Leak tightness

Answer: (C)

Testing pressure regulating devices involves confirming three things: the regulator is set to the correct discharge pressure, its relief mechanism operates to prevent overpressure, and the installation is leak-tight. The regulator must deliver the intended pressure to the system, so accurate setting is essential. The relief valve or relief mechanism protects against excessive pressure if conditions change or the regulator malfunctions, ensuring safety and system integrity. Leak-tightness matters because even with correct settings and functioning relief, any leakage can prevent the system from maintaining the required pressure and can mask underlying improper installation. Together, these checks verify that the device will perform as designed under real service conditions, which is why all these aspects need to be tested.
