What is the maximum inlet pressure for sprinklers that should be maintained?

The maximum inlet pressure for sprinklers is critical for ensuring proper operation and efficiency of the system. Maintaining an inlet pressure of 40 pounds per square inch is generally considered optimal because it strikes a balance between adequate water distribution and preventing damage to the sprinkler heads and piping system.

If the pressure is too low, it may result in inadequate coverage or uneven distribution of water, compromising the system's effectiveness in treating waste. Conversely, if the pressure exceeds this limit, it could lead to physical harm to the fixtures, including breaks or leaks, which not only increases maintenance costs but can also create hazards in the system.

Thus, a maximum inlet pressure of 40 pounds per square inch helps maintain the integrity and functionality of the sprinklers, ensuring that they operate safely and effectively within their designed parameters.
