Which of the following is one of the three test points used in the pressure control service test?

• A. 90 PSI
• B. 150 PSI
• C. 250 PSI
• D. 350 PSI

Answer: (A)

In a pressure control service test, you check how the water system behaves across the operating range by testing at three distinct pressure points. One of these points is the low-end value, which is set around 90 psi. This low point verifies the regulator and controls engage properly as flow starts and that the system can maintain a minimum acceptable pressure under light to moderate demand. It ensures the pump or supply can deliver reliably without dropping below safe pressure when demand is low. The other two test points cover higher pressures for mid- and high-demand scenarios, so the 90 psi value stands out as the designated low-end test point. That’s why 90 psi is the correct choice.
