Which device would you select to improve pressure at fixtures when the main supply lacks sufficient pressure?

• A. Booster pump
• B. Pressure relief valve
• C. Check valve
• D. Flow switch

Answer: (A)

When fixtures suffer from low supply pressure, you need a device that adds energy to the water to raise the pressure going to the outlets. A booster pump does exactly this by drawing from the main supply and increasing the pressure in the distribution system, often controlled by a pressure switch to maintain a chosen setpoint and sometimes paired with a downstream check valve to prevent backflow. This makes the pump the best choice for improving pressure at fixtures when the main supply is inadequate. The other devices serve different purposes: a pressure relief valve protects against overpressure rather than boosting pressure, a check valve prevents reverse flow but does not increase pressure, and a flow switch detects flow and can trigger actions but does not raise pressure on its own.
