Red Seal Sprinkler Fitter Practice Exam

What is the primary role of a fire pump in a sprinkler system?

1. To lower water pressure

2. To increase water pressure

3. To filter water before use

4. To store water for emergencies

The correct answer is: To increase water pressure

The primary role of a fire pump in a sprinkler system is to increase water pressure. Fire pumps are essential components designed to deliver high-pressure water to sprinkler heads, ensuring that the system can effectively control or extinguish fires. In many cases, municipal water supplies may not provide the adequate pressure needed to achieve optimal sprinkler performance during an emergency. Thus, fire pumps are employed to supplement the available water supply, ensuring that adequate flow and pressure are maintained at all times to protect lives and property. This reliable operation is crucial, especially in larger buildings or those with unique construction features that may hinder water distribution. By enhancing water pressure, fire pumps ensure that the sprinkler system can deliver water effectively over the required distance and height, allowing for proper coverage in the event of a fire. The other roles mentioned, such as lowering water pressure, filtering water, or storing water, do not align with the main purpose of a fire pump in a sprinkler system, which centers around the necessity to provide sufficient pressure for effective firefighting capabilities.
