Why is it important to test the discharge pressure gauges and flowmeter?

Testing the discharge pressure gauges and flowmeter is essential because it ensures that the apparatus delivers the correct amount of water under the necessary pressure. If these gauges are inaccurate, it could lead to a situation where either dangerously insufficient or excessive amounts of water are supplied to a fire, compromising firefighting efforts and increasing the risk of failure in extinguishing the fire effectively. Correct readings are crucial for determining adequate water flow and pressure, which are vital during firefighting operations to ensure safety and efficiency.

While complying with NFPA standards is important, and they may include testing protocols, the immediate concern in the context of operation during a fire response is the accurate measurement of water delivery to protect lives and property. Fuel efficiency and tire pressure are not relevant to the direct function of the discharge pressure gauges and flowmeter in firefighting operations.
