What should be done if a pressure gauge fails?

When a pressure gauge fails, the most prudent action is to replace it immediately. A faulty gauge can give incorrect pressure readings, which may lead to unsafe operating conditions or equipment failure. Pressure gauges are critical for ensuring that the system operates within safe parameters. If the gauge is malfunctioning, it may not accurately reflect the pressure within a boiler or other pressurized system, which is essential for safety and efficiency.

Monitoring a malfunctioning gauge or attempting to calibrate it may provide a temporary solution but does not address the underlying issue of its reliability. Ignoring the problem can lead to serious hazards, including potential equipment damage or operational accidents. Therefore, replacing the faulty pressure gauge is the best practice to ensure accurate monitoring and maintain safety standards.
