What is the system pressure used for leak detection?

The system pressure used for leak detection is typically set at 125 psig. This pressure is considered an adequate level to ensure that leaks can be detected effectively while also being manageable within the operational limits of many systems. By using 125 psig, the testing can accurately simulate potential operating conditions without exceeding safety thresholds. This level balances sensitivity and safety, allowing technicians to identify any leaks in the system that need to be addressed.

Other pressures, while they may be used in varying contexts, do not represent the standard practice for most leak detection protocols. Using a pressure that is too low could result in missed leaks, whereas pressures that are too high could pose safety risks or damage equipment.
