When adjusting a system regulator, what is the maximum lockup pressure allowed?

The maximum lockup pressure allowed when adjusting a system regulator is 14 inches. Lockup pressure refers to the pressure at which the regulator is closed off and does not allow any gas to flow through. It is critical to maintain this pressure within safe limits to ensure proper functioning of the regulator and prevent potential damage or safety hazards in the system.

Setting the lockup pressure too high could lead to excessive stress on the regulator and associated piping, possibly causing leaks or failure of components. A lockup pressure of 14 inches strikes a balance, ensuring the system operates within established safety and efficiency thresholds, without risking the integrity of the equipment.

Understanding these operational limits is crucial for maintaining a safe and reliable gas distribution system.
