What is the typical PSI range for most residential irrigation systems?

The typical PSI (pounds per square inch) range for most residential irrigation systems is generally considered to be between 30 to 50 PSI. This pressure range is ideal because it provides sufficient force to distribute water effectively to the plants and lawn without causing damage to the irrigation components or the landscape itself.

Operating within this PSI range ensures that spray heads function properly to cover the desired areas without overshooting or creating runoff. Additionally, it allows for adequate water distribution without leading to excessive misting or evaporation, which can be common at higher pressures.

While lower pressures, such as those around 10 to 20 PSI, may not provide adequate coverage, and pressures above 60 PSI can lead to inefficiencies and potential system damage, the 30 to 50 PSI range offers a balance between efficiency and safety for residential irrigation systems. This makes it the recommended range for typical use.
