How often are the accuracy of pressure gauges and sensors on a fire pump checked?

• A. daily
• B. weekly
• C. monthly
• D. yearly

Answer: (D)

Accurate pressure readings are essential because the fire pump’s start and stop points, as well as overall performance checks, rely on true pressure measurements. Over time, gauges and sensors can drift due to wear, vibration, temperature changes, or aging components, so periodic calibration is needed to keep readings trustworthy. Calibrating or checking the accuracy of pressure gauges and sensors on a fire pump is typically done on a yearly basis. This interval balances practicality with the need to catch drift before it affects operation. More frequent checks might be required by manufacturers for certain devices or in high-criticality environments, but the standard maintenance expectation is annually. Daily or weekly checks can confirm that the system is responding and that indicators appear to function, but they don’t substitute for calibration. If readings seem off during any test, calibration should be performed sooner to ensure trustworthy measurements and proper pump performance.
