How does increased PSI affect an irrigation system?

Increased PSI (pounds per square inch) in an irrigation system generally leads to an increase in both flow and throw. When the pressure in the system rises, it enhances the ability of water to be forced through the irrigation lines and out of the sprinkler heads.

Higher pressure typically results in a greater volume of water being delivered per unit of time, thereby increasing the flow rate. This also affects the throw distance, which is the distance the water travels when it leaves the sprinkler nozzle. With increased pressure, sprayers can project water further, providing a broader coverage area for irrigation.

While maintaining baseline efficiency is crucial for irrigation systems, increased PSI is specifically associated with enhanced performance in terms of flow and throw. Therefore, this option accurately reflects the relationship between increased pressure and the effectiveness of water delivery in an irrigation system.
