What is the typical maximum duration for a hydrostatic test performed on a sprinkler system?

The maximum duration for a hydrostatic test performed on a sprinkler system is typically up to 2 hours. This timeframe is established to ensure that the system is adequately tested for leaks under pressure while also maintaining efficiency in the testing process. A hydrostatic test involves filling the system with water and pressurizing it to a specified test pressure. Performing this test for 2 hours allows sufficient time to monitor for any potential leaks or weaknesses in the system's components without unnecessarily prolonging the process. Extended durations beyond this may not provide additional benefits and can introduce complications, such as potential water quality issues or increased risk of damage to system components.
