What action must be taken if the propane pressure exceeds 14 inches water column during a regulator lock up test?

Adjust the regulator
Replace the regulator
Increase the pressure limit
Perform a leak test

The correct answer is: Replace the regulator

If the propane pressure exceeds 14 inches of water column during a regulator lock-up test, the appropriate action is to replace the regulator. This is because regulators are designed to maintain a specific pressure range to ensure that the propane supply is safe and operates effectively. An excessive pressure reading indicates that the regulator is malfunctioning, failing to control the flow correctly, or unable to maintain its set pressure. Continued operation with a regulator that is not functioning properly presents a safety hazard, potentially leading to system failures, leaks, or even fire hazards. Replacing the regulator resolves these concerns and ensures that the propane system operates within safe parameters. While adjusting the regulator might sound like a potential solution, it is not advisable if the unit shows signs of failure indicated by the high pressure. Similarly, increasing the pressure limit could exacerbate safety issues rather than fix the underlying problem with the regulator. Performing a leak test is also essential, but it should be done after addressing the regulator issue to ensure overall safety. Thus, replacement is the best course of action to ensure safe and proper operation of the propane system.
